How can I use powershell and 7zip ( 7za.exe ) to ZIP a folder while excluding certain file types?
I tried this:
cd "C:\path\to\folder to zip"
7za.exe a "C:\path\to\newZip.zip" -mx3 -x!*.txt -x!*.pdf
But that returns:
.txt: WARNING: The system cannot find the file specified.
.pdf: WARNING: The system cannot find the file specified.
and doesn't ZIP anything- just creates an empty ZIP file.
I have also tried this:
cd "C:\path\to\folder to zip"
Get-ChildItem "C:\path\to\folder to zip" -Recurse -Exclude *.txt, *.pdf | 7za.exe a -mx3 "C:\path\to\newZip.zip" $_.FullName
But that ZIPs everything in the "C:\path\to\folder to zip" folder instead of excluding anything..
Thank you for any help you can provide.

Your second attempt is almost correct.
Your command to call 7-zip need to be wrapped in a for-each block, otherwise the $_.FullName is resolved to an empty string and 7-zip (in the absence of the input parameters) automatically zips everything in the directory. So change it to this:
Get-ChildItem "C:\path\to\folder to zip" -Recurse -Exclude *.txt, *.pdf | %{7za.exe a -mx3 "C:\path\to\newZip.zip" $_.FullName}
Note that % is an alias to foreach-object.

When using powershell to rename files with their directory name and file name, my code works, except in the first file in a directory, it gives it two copies of the directory name. So the file book1.xlsx in folder folder1 should become folder1book1.xlsx but it becomes folder1folder1book1.xlsx. The remaining files in folder1 are correctly named folder1book2.xlsx, folder1book3.xlsx, etc.
I have a directory, with many sub-directories. In each sub-dir are files that need their sub-dir name added in.
I've been following this code. For me it looks like:
dir -Filter *.xlsx -Recurse | Rename-Item -NewName {$_.Directory.Name + "_" + $_.Name}
I've also tried
--setting the Recurse -Depth 1 so that it doesn't keep looking for folders in the sub-folders.
--using ForEach-Object {$_ | ... after the pipe, similar to this.
--running it in Visual Studio Code rather than directly in PowerShell, which turns it into:
Get-ChildItem "C:\my\dir\here" -Filter *.xls -Recurse | Rename-Item -NewName {$_.DirectoryName + '_' + $_.Name}
--putting an empty folder inside the sub-directory, setting -Depth 2 to see if that will "catch" the recurse loop
I would expect the files to be named folder1_book1.xlsx, folder1_book2.xlsx, folder1_book3.xlsx.
But all of the attempted changes above give the same result. The first file is named folder1_folder1_book1.xlsx [INCORRECT], folder1_book2.xlsx[CORRECT], folder1_book3.xlsx[CORRECT].
A workaround might be writing an if statement for "not files that contain the sub-directory name" as suggested here. But the link searches for a text string not an object (probably not the correct term) like #_.Directory.Name. This post shows how to concatenate objects but not something like #_.Directory.Name. Having to put in an if statement seems like an unnecessary step if -Recurse worked the way it should, so I'm not sure this workaround gets at the heart of the issue.
I'm running windows 10 with bootcamp on a 2018 iMac (I'm in Windows a lot because I use ArcMap). Powershell 5.1.17134.858. Visual Studio Code 1.38.0. This is a task I would like to learn how to use more in the future, so explanations will help. I'm new to using PowerShell. Thanks in advance!
This was a script I created for one of my customers that may help
<##################################################################################################################################
This script can be used to search through folders to rename files from their
original name to "filename_foldername.extension". To use this script
please configure the items listed below.
Items to Congfigure
-$Original
-$Source
-$Destination
-$Files
Also please change the Out-File date on line 29 to today's date ****Example: 2019-10-02****
We've also added a change log file that is named "FileChange.txt" and can be found in the location identified on line 30
>
$Original="C:\temp\test" #Location of ".cab" files copied
$Source="C:\temp\Test" #Location were ".cab" files are stored
$Destination="C:\temp\Test\2019-10-02" #Location were you want to copy ".cab" files after the file name change. Be sure to change the date to the date you run this script. The script creates a folder with todays date
$Files=#("*.cab") #Choose the file type you want to search for
$ErrorActionPreference = "SilentlyContinue" #Suppress Errors
Get-ChildItem $Original -Include "*.cab" -File -Recurse | Rename-Item -NewName {$_.BaseName+"_"+$_.Directory.Name +'.cab'}
New-Item -ItemType Directory -Path ".\$((Get-Date).ToString('yyyy-MM-dd'))"; Get-ChildItem -recurse ($Source) -include ($Files) | Copy-Item -Destination ($Destination) -EA SilentlyContinue
Get-ChildItem $Original | Where {$_.LastWriteTime -ge [datetime]::Now.AddMinutes(-10)} | Out-File C:\temp\test\2019-10-02\FileChange.txt
I’m looking for a solution to rename all files with given name in the directory and subfolders.
E.g.
There is a directory called c:\blah and in this folder, there is one file called BaR.txt and one folder called foo. In the foo folder, there is another file called bAr.txt.
I want to find all files with name bar.txt and change the name of each file to “neo.txt”. It must also be possible to rename the files to lower case as well e.g. bar.txt.
So far, I’ve tried to do this manually using the Windows Explorer in Windows10 but for some weird reason when I try to rename the bulk files there is extra “(1)” sign added to the end of each file name.
I’ve tried to play with PowerShell and I created a command
$_.name -replace 'bar.txt','neo.txt'
But it didn’t work for me.
To do this, you need 2 cmdlets: Get-ChildItem and Rename-Item.
This should work:
Get-ChildItem -Path 'C:\Blah' -Filter 'bar.txt' -Recurse | ForEach-Object {
Rename-Item -Path $_.FullName -NewName 'neo.txt'
}
However, if inside the foo folder there are more subfolders, this code will rename all files called bar.txt (case-insensitive) it finds in all of these subfolders.
If you do not want to go any deeper than the first subfolder in C:\Blah (the one called foo), you can use the -Depth parameter on the command like this:
Get-ChildItem -Path 'C:\Blah' -Filter 'bar.txt' -Recurse -Depth 1 | ForEach-Object {
Rename-Item -Path $_.FullName -NewName 'neo.txt'
}
I'm trying to copy all of the files with .py extension from one directory to a new one using PowerShell, but I don't want to recreate the directory structure. I want this to work recursively as the the py files are in numerous subfolders. In my destination directory, I want nothing but the py files.
Here's what I have now but it copies the directory structure too:
Get-ChildItem "C:\Johns Stuff\Python\" |
Copy -Destination C:\Users\dread\python -Recurse -filter *.py
How about:
Get-ChildItem "C:\Johns Stuff\Python" -File -Filter *.py -Recurse | ForEach-Object {
Copy-Item $_.FullName C:\Users\dread\python -WhatIf
}
The -File parameter (new in PowerShell 3.0 and later) will get only files and not directories.
Of course, remove -WhatIf to actually execute the command.
I must delete files which have been extracted from a zip file, into a folder named after the zip file, i.e.:
\test1.zip -> \test1
My script must find the folder which have the same name as the zip file and delete this folder.
Get a list of all of the Zip files in the directory, then loop over the results and delete any folder with the same name minus the extension, also known as the BaseName.
Get-ChildItem -Filter *.zip | `
ForEach-Object { if (Test-Path $_.BaseName) {
Remove-Item -Recurse -Force $_.BaseName }
}
You can enter the entire command on one line, I have split it up so that it is easy to read on here. I used the following commands in this example:
Get-ChildItem - Creates a object in the pipeline for each file with a .zip extension
ForEach-Object - Simply allows you to perform an action for each object in the pipeline.
Remove-Item - note the use of -Recurse and -Force ensures that the folder is removed even if it contains files, you will not be asked to confirm.
I have a PS script which Zips up the previous months logs and names the zip file FILENAME-YYYY-MM.zip
This works
What I now want to do is copy these zip files off to a network share but keeping some of the folder structure. I currently a folder structure similar to the following;
C:\Folder1\
C:\Folder1\Folder2\
C:\Folder1\Folder3\
C:\Folder1\Folder4\Folder5\
There are .zip files in every folder below c:\Folder1
What I want is for the script to copy files from c:\folder1 to \\networkshare but keeping the folder structure, so I should have 3 folders and another subfolder in folder4.
Currently I can only get it to copy the whole structure so I get c:\folder1\... in my \\networkshare
I keep running into issues such as the new folder structure doesn't exist, I can't use the -recurse switch within the Get-ChildItem command etc...
The script I have so far is;
#This returns the date and formats it for you set value after AddMonths to set archive date -1 = last month
$LastWriteMonth = (Get-Date).AddMonths(-3).ToString('MM')
#Set destination for Zip Files
$DestinationLoc = "\\networkshare\LogArchive\$env:computername"
#Source files
$SourceFiles = Get-ChildItem C:\Sourcefiles\*.zip -Recurse | where-object {$_.lastwritetime.month -le $LastWriteMonth}
Copy-Item $SourceFiles -Destination $DestinationLoc\ZipFiles\
Remove-Item $SourceFiles
Sometimes, you just can't (easily) use a "pure PowerShell" solution. This is one of those times, and that's OK.
Robocopy will mirror directory structures, including any empty directories, and select your files (likely faster than a filter with get-childitem will). You can copy anything older than 90 days (about 3 months) like this:
robocopy C:\SourceFiles "\\networkshare\LogArchive\$($env:computername)\ZipFiles" /E /IS /MINAGE:90 *.zip
You can specify an actual date with /MINAGE too, if you have to be that precise.
How about Copy-Item "C:\SourceFiles\" -dest $DestinationLoc\ZipFiles -container -recurse? I have tested this and have found that it copies the folder structure intact. If you only need *.zip files, you first get them, then for each you call Resolve-Path with -Relative flag set and then add the resultant path into Destination parameter.
$oldloc=get-location
Set-Location "C:\SourceFiles\" # required for relative
$SourceFiles = Get-ChildItem C:\Sourcefiles\*.zip -Recurse | where-object {$_.lastwritetime.month -le $LastWriteMonth}
$SourceFiles | % {
$p=Resolve-Path $_.fullname -relative
copy-item $_ -destination "$DestinationLoc\ZipFiles\$p"
}
set-location $oldloc # return back
