I need a script that copies files that are newer than a specified time (read from a file) from a directory and subfolders to a mirroring folder structure (that needs to be created). However, this needs to take account of date and time, not just date.
I can't seem to find a way to do this using batch / robocopy or another approach. Any suggestions would be appreciated, ideally not using powershell (I realise it can probably do it, but I've never used it and the learning curve seems a bit steep for now).
I can adjust the date/time saved in the file to fit any format.
So, say date-time is 2016-08-17-18-00-00, then
Org\A\1.txt (2016-08-17-18-01-00) > Target\A\1.txt
Org\A\2.txt (2016-08-17-17-00-00) > (not copied, as too old)
Org\B\C\D\3.txt (2016-08-18-09-00-00) > Target\B\C\D\3.txt
I probably need to use a forfiles loop, but not sure how to take account of time as well as date.
#echo off
setlocal enabledelayedexpansion
set compare=201608171800
for /r %%F in (*) do (
set file=%%~fF
for /f "tokens=2 delims=.=" %%I in ('wmic datafile where name^="!file:\=\\!" get lastmodified /format:list') do (
if "%%I" geq "%compare%" for /f "tokens=2,* delims=\" %%A in ("%%~fF") do echo %%~fF -- N:\target\%%B
)
)
you may have to adapt the "2" in tokens=2,* to your needs.
Note: this is slow, because of wmic
because of string comparison this works with %compare% format of YYYYMMDDhhmmss or YYYYMMDDhhmm or even YYYY.

Currently, I have to upload a bunch of excel sheets to a network shared folder. Each of these files has the date they were created appended at the end of the filename. Then I have to remove the earlier duplicates leaving just the latest dated versions.
Basically it looks likes this...
Before:
apples 2019.07.01.xlsx
apples 2019.07.07.xlsx
oranges 2019.07.01.xlsx
bananas 2019.07.01.xlsx
After:
apples 2019.07.07.xlsx
oranges 2019.07.01.xlsx
bananas 2019.07.01.xlsx
I stumbled upon a possible solution, which was to create a batch-file to recursively go through the folder and do this. However, I am unsure where to start.
I read this other stackoverflow article, which is pretty close to what I want to do but I am having trouble adjusting it to my needs. Any assistance would be appreciated.
Edit2: this code worked for me:
#(
SetLocal EnableDelayedExpansion
ECHO OFF
SET "_PathToCheck=Y:\T\DT"
SET "_FileGlob=PLOG - * - ????.??.?? - *.xlsx"
SET "_CurrentFile="
)
FOR /F "Tokens=1-2* Delims=-" %%A IN ('DIR /A-D /O-N /B "%_PathToCheck%\%_FileGlob%"') DO (
IF /I "!_CurrentFile!" EQU "%%A-%%B" (
ECHO.Deleting: "%_PathToCheck%\%%A-%%B-%%C"
DEL /F /Q "%_PathToCheck%\%%A-%%B-%%C"
) ELSE (
ECHO.
ECHO.New File Found: "%%A-%%B"
ECHO.-----------
ECHO.Retaining: "%_PathToCheck%\%%A-%%B-%%C"
SET "_CurrentFile=%%A-%%B"
)
)
You may use the same approach you would use if you do this job by hand: review the file list and every time that a file appear with the same name than the previous one, remove the previous one... Simple! Isn't it? ;)
#echo off
setlocal EnableDelayedExpansion
rem Initialize the "previous name"
set "lastName="
rem Process files in natural order, that is, the same order showed in the question
rem and set %%a to name and %%b to rest: date plus extension
for /F "tokens=1*" %%a in ('dir /B /A:-D /O:N *.xlsx') do (
rem If previous name is not the same as current one
if "!lastName!" neq "%%a" (
rem Just update previous name and date
set "lastName=%%a"
set "lastDate=%%b"
) else (
rem Remove the previous file
ECHO del "!lastName! !lastDate!"
rem and update the previous date
set "lastDate=%%b"
)
)
This solution assumes that the name and the date parts are separated by exactly one space...
EDIT: New method added, after several confusing changes made by the OP
#echo off
setlocal EnableDelayedExpansion
set "lastName="
for /F "delims=" %%a in ('dir /B /A:-D /O:N *.xlsx') do (
set "currName="
set "currFile="
for %%b in (%%~Na) do (
set "part=%%b"
set "currFile=!currFile! !part!"
if "!part:.=!" equ "!part!" set "currName=!currName! !part!"
)
if "!lastName!" neq "!currName!" (
set "lastName=!currName!"
set "lastFile=!currFile!"
) else (
ECHO del "!lastFile:~1!.xlsx"
set "lastFile=!currFile!"
)
)

Here is the newest version for you Greg.
Although originally I and a couple of others wrote versions which would work for date modified using a different logic (create variables for all of the files' names then sort them again, or do sets of compares) I realized we could still accomplish the goal in a single loop and without needing so many temp variables and without having to have more complex logic in that scenario and this one, so I took a few minutes and created that version.
Essentially we just need to define a variable with the File's name that has already been found, since we know they are ordered correctly date-wise, and only need to worry about removing the duplicate named files.
To do so we can use SEt or IF DEFINED, I prefer IF DEFINED here since I can use regular IF ( ) THEN ( ) ELSE ( ) logic as already defined in the script. (Note the items in Italic here are not terms that can be used in a CMD script, but I am writing them to clarify the normal logic of the IF construct)
We could use SET "[Variable Name]" instead, and test if success or failure using || or &&, but that would be more re-write and unnecessary here.

Screenshot confirming the Script works and showing the Output and results:
Essentially this does the same thing as in my original version only now we know that we should be looking for the Hyphens
IE:
We use DIR to Sort the File names in a reversed sort order, this will mean that files that have a newer date it will appear before those with older dates.
This simplifies the logic for deleting the files, and is the crux of my original solution as well.
Because of using that method we only need to check if the first part of the file name (the part before the date) is the same as the previous file found.
We do this by creating a variable to hold the name of the current file _CurrentFile and set it empty, so on the initial check, it will not match any file name.
If _CurrentFile matches the first part of the file name (again, the part before the date) o the file dir found, then we can safely delete it.
If _CurrentFile does not match the interesting portion of the file reported by the DIR cmd, then we update the _CurrentFile variable to that new value and move on to the next file result to test.
As you are unfamiliar with cmd/batch scripting, I would like to take a minute to go into more detail about what the script is doing and why for you so you can go forward yourself:
First I should note that we have a few options on how to iterate the files, most commonly for, for/F, and For files are common go-to for looping over files, sometimes with a DIR cmd in a for /F alternatively with a WMIC file list (although, thankfully WMIC is finally getting deprecated in favor of Powershell).
As we know you simply wat to Choose based off its Filename and the date stored in the file name, then using a dir cmd to sort by Name will be a pragmatic method to do the matching quickly
Now onto what each part of the script is doing
#(
Parenthesis create code blocks in CMD and Batch Script, everything within a given Parenthesis will be evaluated at the same time.
By placing an # in front of the parenthesis any commands with it ( And not within further parenthesis, or after a DO ) will not be echoed to the screen. This is to stop this section form showing up and cluttering output.
SetLocal EnableDelayedExpansion
We are turning on Delayed Expansion, to allow us to easily evaluate the contents of the variables inside of a for loop by referencing them with !_var! instead of %_Var%, technically we can get away without this if any of your filenames have ! in them, we should disable this and re-write it a bit, if not then it's fine.
ECHO OFF
I am stopping the script from echoing every line it is doing so we have less cluttered output. Setting this command means I no longer have to use # in front of further commands within this code block or future code outside this block.
SET "_PathToCheck=Y:\T\DT"
SET "_FileGlob=PLOG - * - ????.??.?? - *.xlsx"
SET "_CurrentFile="
)
Setting the variables and closing the code block with a closing parenthesis seems self-explanatory except for one _FileGlob
This is a standard File Glob it is used to match the name of the file you want to have considered for comparison.
* matches any character any number of times, ? matches any character once.
This ensures that if we encounter files which don't conform to the format we expect we can skip them.
If the need required a more explicit matching, we might use a glob of *.xlsx and use FINDStr to check against a regex pattern to make sure the format was very exactly the one needed.
in this next part
FOR /F "Tokens=1-2* Delims=-" %%A IN ('
DIR /A-D /O-N /B "%_PathToCheck%\%_FileGlob%"
') DO (
[Code]
)
Now I am going to go a little out of order here:
We are using DIR to quickly sort the files by Their Name in reverse order and return just the filenames. DIR is extremely fast at doing this, so it's preferable if you are doing a little sorting rather than matching the files using IF compares later. We utilize the file glob as mentioned above to ensure only files we want to evaluate are returned.
The Option /A-D ignores directories, /B will only output the file name (since we aren't recursing) Then, we have /O-N -- /O is "Order By" the Option N sorts by Name ascending, while -N sorts by name in Reverse (Descending) Order (IE Z-A 9-0), so we can be assured that the file with the name that has the newest date will be the first one we find.
This is all placed inside a For /F Loop which is a way to parse the output of a command. We use Delims=- to "Tokenize" or Split-up the strings FOR is receiving from the DIR command. We Tell FOR what Variable names to store the Tokes in using %%A (Variables are as follows: "? # A B C D E F G H I J K L M N O P Q R S T U V W X Y Z [ \ ]" OR "_ `` a b c d e f g h i j k l m n o p q r s t u v w x y z" { ( More info here https://ss64.com/nt/for_f.html ) ), Variables we be assigned to Tokens starting with the one you chose.
When we specify the tokens to pick, Tokens=1-2*", specifically 1-2 means to take the first Token through the second token, and store them in the First N variables (where N = the number of variables in the set 1-2, ie %%A and %%B for our purposes), and * means stop tokenizing anything after any tokens mentioned prior to this point, and place all of the remaining portions of the line into the next variable (%%C).
Because we are tokenizing use the Hyphen as a delimiter, we now that the first two tokens will be PLOG and [Name to Compare while the date and the rest of the file name will be in the 3rd token.
In the DO ( ) section we are going to go on and process the info returned by each line and stored in our tokens.
Lets go on to examine the code within the DO ( )
IF /I "!_CurrentFile!" EQU "%%A-%%B" (
ECHO.Deleting: "%_PathToCheck%\%%A-%%B-%%C"
DEL /F /Q "%_PathToCheck%\%%A-%%B-%%C"
) ELSE (
ECHO.
ECHO.New File Found: "%%A-%%B"
ECHO.-----------
ECHO.Retaining: "%_PathToCheck%\%%A-%%B-%%C"
SET "_CurrentFile=%%A-%%B"
)
This is probably familiar to you enough as you are used to VBA, but we are testing the value of the variable _CurrentFile to the First Two Portions of the string, which we know are the entire portion of the file name up to the Date, and we need to add the Hyphen back in because when FOR splits by tokens it removes those tokens.
We check is the _CurrentFile variable ia a match for the currently returned file name's portion up to, but not including the date.
If this matches, we delete (Del) the file because we have already seen the file once before so this is one that is older.
We use the /F Option to Force deleting read-Only Files, and we use /Q to stop it from prompting us to confirm the deletion of each file.
We also ECHO. that we are deleting the file we found to note what the script is doing.
) ELSE (
If this does not match, that means this is a new file we haven't encountered for, and must be the first one returned, in which case we want to keep it because we know from the sort of Dir that it will be the interesting file.
Therefore on a non-match, we change the _CurrentFile variable to hold the value of the first two tokens %%A-%%B to use in future checks of the results returned.
We also ECHO. that we found the file and are retaining it to give a nice little indicator of what the script is doing.
A further note on ECHO -- Although I like how Echo. looks, ECHO( is safer to use, and I prefer it for that reason, but it is more confusing for folks who are unfamiliar with cmd scripts as the Open parenthesis looks like I have either a typo or an unclosed code block and can lead to people thinking it causes some problem. So for this reaosn, I try to avoid using ECHO( in favor of ECHO. when ECHO. will do.
Original Post and Versions Which used the incorrect format
You can make this a quite simple script that basically finds each unique name and keeps the 1st one so long as your names are in YYYY.MM.DD.xlsx format by pre-sorting the names so that the one with the newest date in the name one is always the first file encountered.
The Space is guaranteed? Optional?
to do this you need to use a FOR /F loop to parse the output from DIR ordered by (/O) Name Descending (-N)
DT.CMD:
#(
SetLocal EnableDelayedExpansion
ECHO OFF
SET "_PathToCheck=Y:\T\DT"
SET "_FileGlob=* ????.??.??.xlsx"
SET "_CurrentFile="
)
FOR /F "Tokens=*" %%A IN ('DIR /A-D /O-N /B "%_PathToCheck%\%_FileGlob%"') DO (
SET "_TFile=%%~nA"
SET "_TFile=!_TFile:~0,-10!"
IF /I "!_CurrentFile!" EQU "!_TFile!" (
ECHO.Deleting: "%_PathToCheck%\%%~A"
DEL /F /Q "%_PathToCheck%\%%~A"
) ELSE (
ECHO.
ECHO.New File Found: !_TFile!
ECHO.-----------
ECHO.Retaining: "%_PathToCheck%\%%~A"
SET "_CurrentFile=!_TFile!"
)
)
We then simply need to compare the names of the files except for the Trailing YYYY.MM.DD.xlsx, and if the File is the 1st with that name we keep it, as we know it will be the newest.
If the name is a duplicate we can delete it because we know we already skipped the newest.
Example Output:
Y:\>Y:\t\DT.cmd
New File Found: bananas
-----------
Retaining: "Y:\T\DT\bananas 2019.07.01.xlsx"
New File Found: oranges
-----------
Retaining: "Y:\T\DT\oranges 2019.09.01.xlsx"
Deleting: "Y:\T\DT\oranges 2019.07.11.xlsx"
New File Found: apples
-----------
Retaining: "Y:\T\DT\apples 2019.07.07.xlsx"
Deleting: "Y:\T\DT\apples 2019.07.01.xlsx"
If your Date format is instead YYYY.DD.MM.Xlsx
Then you will need to go through an extra hoop or two.
Essentially in that scenario, we can do the following:
save the File name as a variable with the corrected (sortable) version of the file name (YYYY.MM.DD format) and then sort it and then compare the array of variables, deleting the ones which are not newest.
Here is that version DT_DM.CMD:

Now, both of these examples Assume that you ALWAYS want whatever file is Named with the Newest Date, not the most recently modified file
This is probably the case as I know I usually want to have that scenario when working with my own dated files, in case someone or some process came along and modified the files, or I saved more than one out of order.
But just in case you really wanted to just retain the most recently modified file, we can Use the same concept as in the second version and save the Real Modified time to the Variables instead of the date on them.

Example of First Script Running ad results:
I have a script that needs to connect to an ftp server and download a file that is only created on Sunday and Sunday's yyyy-mm-dd-hh-mm-ss is appended to the file name. I need to find the last Sunday's date (based on today's date, I assume) and convert it to yyyy-mm-dd (I don't care about the time) so I can construct the filename in my ftp script. I have searched a lot of threads on this and other sites, but I'm kind of a novice at batch syntax. I cannot make assumptions about the date format on the machine that will run this script, but it will be in the same timezone as the ftp server and it will be running at least Windows 7. I thought about using the PowerShell solution in HOW to find last SUNDAY DATE through batch but I've read there are issues with PS script portability. Any help is greatly appreciated. Let me know if I need to provide more detail. Thanks!
(Get-Date).AddDays(-(get-date).dayofWeek.value__)
A couple years ago I wrote a batch script to find yesterday's date. I made it able to calculate 'yesterday' based on today's date. It takes into account months ending on the 30th or 31st, and even the next few leap years. The way I wrote it expects the date to be in the format 'Wed 02/24/2016' or 'ddd MM/DD/YYYY', so it may not be useful to you.
As I look at it now, it's probably more complicated than it needs to be and could probably use some cleanup, but it worked for my purposes. You might be able to modify it somehow to make it find last Sunday, instead of yesterday.

Working with date and time using pure batch can be done, but it is not very convenient.
The GetTimestamp.bat utility makes date/time computations and formatting simple within a batch context. It is pure script (hybrid JScript/batch) that runs natively on any Windows machine from XP onward. The previous link points to the most recent version. The utility was first introduced with a number of examples at http://www.dostips.com/forum/viewtopic.php?t=4847.
Full documentation is available from the command line via getTimestamp /?, or getTimestamp /?? for paged output.
With GetTimestamp, the solution can be as simple as:
#echo off
:: Get the current day of the week, with 0=Sunday, 6=Saturday
:: to be used as an offset from today to get the most recent Sunday
call getTimeStamp -f {w} -r offset
:: Use the offset to get the most recent Sunday in YYYY-MM-DD format
call getTimeStamp -od -%offset% -f {iso-dt} -r lastSunday
:: Show the result
echo lastSunday=%lastSunday%
Try the following from a batch file:
for /f "usebackq" %%d in (`powershell -noprofile -command "'{0:yyyy-MM-dd}' -f [DateTime]::Now.AddDays(-1 * [DateTime]::Now.DayOfWeek)"`) do set "lastSunday=%%d"
echo %lastSunday%
:: -> e.g., "2016-02-21", when run on 2016-02-25
To try this directly on the command prompt, replace %%d with %d.
The PowerShell expression at the heart of the command,
[DateTime]::Now.AddDays(-1 * [DateTime]::Now.DayOfWeek),
which calculates the date of the most recent Sunday, was gratefully borrowed from the answer that you link to in your question.
'{0:yyyy-MM-dd}' -f ... applies the desired yyyy-mm-dd formatting to the date.
powershell -noprofile command ... invokes the PowerShell expression and outputs its result to stdout.
for /f "usebackq" %%d in (`...`) do set lastSunday=%%d captures the output from the PowerShell command and assigns it to batch variable lastSunday.
While invoking PowerShell for just one command from a batch file will be slow, being able to calculate the desired date so conveniently probably outweighs performance concerns.
Looping through files in a Specific Date/Time Order
Hi All,
I'm struggling to write a small addition to my batch file I have been using for a while. Firstly, here are some example files names I would be dealing with:
output.log, output.log.1, output.log.2, ..., outlput.log.199
The input file set may contain just 1 or a few of the above files (always in the order shown, newest first, oldest last), or all 200 files.
What am I attempting to do
The batch file is used to do several things with these file, such as copy them into a new directory, or create a parameter list to pass them into another command. In general, what I have works well, it did what I wanted at the time, however, processing all 200 file in a potential file set is time consuming. What I am now looking to do is limit the number of processes file, to extract just the first, say 20 files, or (if there are less than 20 files), all of them.
The problem I have is that the FOR loop I am using loops though the files by name order, not date/time order. Therefore, if I stop after 20 iterations, I end up with:
output.log, output.log.1, output.log.10, outlput.log.100, outlput.log.101, ...
I need to be able to loop through the file set in date/time order (newest first). I do not know what the date range will be, or if the files are at specific intervals, just the log file will always be as per the first list.
The Code I have
setlocal EnableDelayedExpansion
Set SnapDir=C:\Snaps\
Set SupportLog=unified_support.log
Set LogDir=\var\log
Set ParsedLogDir=\var\log\parsed
set PARAMS=
set /A NumberSupportFiles=20
Set /A StartSupportCount=0
if [%1]==[] goto :eof
:loop
rem Create a Parameter list of all the Log files, Copy File then stop after a set number of interations
for %%A in ("%SnapDir%%~n1%LogDir%\%SupportLog%*") do (
set PARAMS=!PARAMS! "%%A"
copy %%A "%SnapDir%%~n1%ParsedLogDir%\"
set /A StartSupportCount+=1
if !StartSupportCount! EQU %NumberSupportFiles% goto :jump
)
:jump
pause
As mentioned, this kinda works, it loops through the first 20 files in the file set, but the file order is by name not date/time.
From what I have read so far, any date/time manipulation appears to need an exact reference point or specific delimitation, and I can't see a way to order the set before looping. Is this possible?
You are almost done, you only need to replace the for loop by a for /F, that parses the output of dir /B A:-D /O:-D, which constitutes a list of files sorted by modification date in decending order (newest first):
#echo off
setlocal EnableExtensions EnableDelayedExpansion
Set "SnapDir=C:\Snaps\"
Set "SupportLog=unified_support.log"
Set "LogDir=\var\log"
Set "ParsedLogDir=\var\log\parsed"
set "PARAMS="
set /A NumberSupportFiles=20
Set /A StartSupportCount=0
if "%~1"=="" goto :EOF
:LOOP
rem Create a Parameter list of all the Log files,
rem Copy File then stop after a set number of interations
for /F "eol=| delims=" %%A in ('
dir /B /A:-D /O:-D "%SnapDir%%~n1%LogDir%\%SupportLog%*"
') do (
set "PARAMS=!PARAMS! "%%~A""
copy "%SnapDir%%~n1%LogDir%\%%~A" "%SnapDir%%~n1%ParsedLogDir%\"
set /A StartSupportCount+=1
if !StartSupportCount! EQU %NumberSupportFiles% goto :JUMP
)
:JUMP
pause
endlocal
exit /B
I have a series of files that have long filenames. For each filename that contains a hyphen I would like to keep the substring in position 6-8, append the _FM07_FY14.prn to the name and ignore the rest of the original filename. The new extension is now .prn. The two digits 07 stands for the month and 14 is the year. The month and year can be found from the "date created" property. Will appreciate it if you can show me how to automatically capture this mm and yy from the date created. Hardcoding this part is okay too since I can sort files by created dates and put them in separate folders.
For example
aaaaaD07.dfdd-1234.A.b.1233 new filename will be D07_FM01_FY14.prn
bbcbaA30dls-d343.a.123d new filename will be A30_FM01_FY14.prn
cdq0dG12ir3-438d.dfd.txt new filename will be G12_FM01_FY14.prn
This is the .bat file I come up with after reading many posts on here, and I don't know how to extract the mm and yy so I hard code it. I am not familiar with Powershell. I can only handle a .bat or .cmd file and run it at the command prompt. Any and all help will be highly appreciated. Thanks!
#ECHO OFF
SETLOCAL
for %%F in (*.*) do (
SET "name=%%a"
set "var=_FM01_FY14.prn"
ren *-* "%name:~6,8%var%"
)
*endlocal*
#ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
SET "sourcedir=U:\sourcedir\one"
PUSHD %sourcedir%
FOR /f "delims=" %%a IN (
'dir /b /a-d "*" '
) DO (
SET name=%%a
SET fdate=%%~ta
ECHO(REN "%%a" "!name:~5,3!_FM!fdate:~3,2!_FY!fdate:~8,2!.prn"
)
popd
GOTO :EOF
You would need to change the setting of sourcedir to suit your circumstances.
The format that I use for date is dd/mm/yyyy If yours is different, then you'll need to change the offset in the !fdate:~m,2! phrases. The value of m is the offset into the date string from the first character (the second parameter is the number of characters to select.)
The required REN commands are merely ECHOed for testing purposes. After you've verified that the commands are correct, change ECHO(REN to REN to actually rename the files.
Hey guys, I'm looking for a batch file to tell me if certain folders have been modified today (I'll run it every morning). I'm happy to specify each of the folders to be to be queried, I just haven't been able to find anything that meets my requirements yet. If anyone knows off the top of their head what the code for the .bat would be, that would be awesome :) Thanks in advance.
Here's a batch file that should do the trick:
#echo off
setlocal ENABLEEXTENSIONS ENABLEDELAYEDEXPANSION
for /D %%Q IN (*.*) DO (
set FILETIME=%%~tQ
if "!FILETIME:~0,10!"=="%DATE:~4%" echo %%Q
)
This works by comparing the date-part of the file timestamp against the current date.
As written, it checks directories in the current directory, but you could replace *.* with whatever filespec you want to test (or pass it in as an argument).
I don't know if this will work on systems with anything other default English/US regional settings, but it could probably be tweaked to make it work, if it doesn't already. I also don't know what would happen if the system is shared between users in different time-zones.
you can use a vbscript
Set objFS = CreateObject( "Scripting.FileSystemObject" )
strFolder = WScript.Arguments(0)
Set objFolder = objFS.GetFolder(strFolder)
If DateDiff("d", Now, objFolder.DateLastModified ) = 0 Then
WScript.Echo "0"
End If
in your batch file (or command line)
C:\test>cscript //nologo test.vbs myFolderName
use a for loop to catch the output. (Or you can even do everything in vbscript )
