i have file names that have a "-" (hyphen) in the filename. I am trying to create a folder for each filename and move the file to the folder.
here is what I am trying to use:
dir | %{
$id = $_.Name.SubString(0,5);
if(-not (Test-Path $id)) {mkdir $id};
mv $_ "$id\$_";}
The issue is, some of the file names have less than 5 characters before the hyphen, so for those folders the hyphen is being added to the folder name. I've tried to use the Split verbiage, but I am stuck on syntax.
a couple of filenames examples are below:
A1909-6628.txt
A963-6634.txt
thanks in advance for your help
try this
#split return an array
$id = ($_.Name -split '-')[0];
You're pretty much on the right track, and you've mentioned the -split operator which is all you really need.
Get-ChildItem | ForEach-Object -Process {
$id = $_.BaseName.split('-')[0];
if((Test-Path $id) -eq $false){Mkdir $id}
Move-Item -Path $_.FullName -Destination $id
}
Without modifying your code too much, i added the split at the hyphen then selectin the first value after the split.
try this:
Get-ChildItem -file -filter "*-*" | %{
#extract first part of file
$Part1=($_.BaseName -split '-')[0].Trim()
#create directory if exist
$NewFolderName="{0}\{1}" -f $_.DirectoryName, $Part1
New-Item -ItemType Directory -Path $NewFolderName -Force -ErrorAction SilentlyContinue
#prepare new filename
$NewPathFile="{0}\{1}" -f $NewFolderName, $_.Name
#move file into new directory
Move-Item $_.FullName $NewPathFile
}
I have a a bunch of language folders present in a directory under E:\Data\ like hu-hu, de-de etc.. on the other hand i have a bunch of file names in G:\ that contain the part of folder name for e.g.
amd64.de-de_OCR.cab,amd64.handwriting.de-de.cab
I need to copy all matching file names based on the foldername
for e.g. de-de should copy all matching files in G:\ i.e. both amd64.de-de_OCR.cab,amd64.handwriting.de-de.cab
This is the code i have so far but it is not copying over the files, and i am not sure how to proceed next, any help is appreciated.
$listfoldername = Get-ChildItem -Path "E:\Data" -Recurse -Directory -Force -ErrorAction SilentlyContinue | Select-Object Name
$destfolder = Get-ChildItem -Path "E:\Data" -Recurse -Directory -Force -ErrorAction SilentlyContinue | Select-Object FullName
$filename = Get-ChildItem -file G:\
if($filename -like $listfoldername)
{
Copy-Item -Path $filename -Destination $destfolder
}
There's a few issues with your code
The main issue with your code is that you are trying to use the -like operator to compare two objects (your object containing the directories you wish to move files to, and the object containing the files.
What you need to do is loop through each file and directory, one by one, to determine if the directory name (e.g. "hu-hu" is found in the filename (e.g. amd64.hu-hu_OCR.cab)
You'll want to use the wildcard indicator "*" with the -like operator (e.g. "*hu-hu*")
This below code snippet should do the trick. I tested using the file and folder names you've provided.
"G:" contains the folders:
de-de
hu-hu
us-us (note, I added this to make sure the code did not match this directory)
"E:\Data" contains the files
amd64.de-de_OCR.cab
amd64.handwriting.de-de.cab
amd64.handwritinghu-hu.cab
amd64.hu-hu_OCR.cab
$FileDirectory = "G:" # Change to "G:\", the trailing slash breaks syntax highlight on SO
$DataDirectory = "E:\Data"
$listfoldername = Get-ChildItem -Path "$DataDirectory" -Recurse -Directory -Force -ErrorAction SilentlyContinue | Select-Object Name
$filename = Get-ChildItem -file "$FileDirectory"
#Loop through each file one at a time
foreach ($file in $filename) {
# Then, loop through each folder one at a time
foreach ($folder in $listfoldername) {
# Set the current filename and listfoldername to variables for later -like operator
$FileString = $file.Name
$FolderString = $folder.Name
# If the current file "is like" the current folder name
if($FileString -like "*$FolderString*")
{
# Set the name of the current folder to a variable
$DataFolder = $folder.Name
Copy-Item -Path "$FileDirectory\$FileString" -Destination "$DataDirectory\$DataFolder"
} else {
Write-Output ("$FolderString pattern not found in $FileString")
}
}
}
I think you should start off by getting a list of possible language target folders. Then loop over the path where the files are, filtering their names to have at least the dash in it and next test if any of the language target folders matches the filename.
Something like this:
$langFolder = 'E:\Data'
$fileFolder = 'G:\' #'# dummy comment to fix syntax highlighting in SO
# get a list of the language folders
# if the languages folder has multiple subdirectories to include, add -Recurse here
$targetFolders = Get-ChildItem -Path $langFolder -Directory
# get a list of FileInfo objects for the files in the G:\ path
# if you need to search subdirectories aswell, add -Recurse here
$files = Get-ChildItem -Path $fileFolder -File -Filter '*-*.*'
foreach($file in $files) {
# check if a language name matches the file name
foreach($folder in $targetFolders) {
if ($file.BaseName -like "*$($folder.Name)*") {
# we have found a matching language target directory
$file | Copy-Item -Destination $folder.FullName
break # exit this folder foreach loop and get on with the next file
}
}
}
P.S. If all the files are .cab files you could speed up by setting the Filter to '*-*.cab' in line $files = Get-ChildItem ...
I'm Trying to move files containing "Sxx" in their names to folder named "Sxx".
for example:
file1: S01E12.srt ----> /S01/S01E12.srt
file2: S03E14.jpg ----> /S03/S03E14.jpg
etc.
So i came up with these codes for creating folders using files having "Sxx" in their names and then moving them into the right folders.
For creating folders:
foreach ($name in (Get-ChildItem -File | % {$_.BaseName -replace 'E\d{2}',''}))
{
if ($name -like 'S*') {
New-Item -path "$name" -ItemType Directory
}
}
For moving files:
get-childitem -File | where {$_ -like "S01*"} | move-Item -Destination "S01*"
get-childitem -File | where {$_ -like "S02*"} | move-Item -Destination "S02*"
...
etc.
Any idea how to replace hardcoding method for moving part?
If you have any advice or better code for any part that would be awesome too.
Below is my code. I created two foreach loops to go once through all files and afterwards through all folders. I used a substring to get part of the file names.
$files = Get-ChildItem -File -Path C:\users\Lenovo\Desktop\Test
$dir = Get-ChildItem -Path C:\users\lenovo\Desktop\Test -Directory
foreach ($item in $files) {
foreach ($folder in $dir)
{
if (($item.Name).Substring(0,3) -like $folder.Name)
{
Move-Item -Path $item.FullName -Destination $folder.FullName
}
}
}
I create four files with S01.txt to S04.txt and it was working. To test whether your variable is empty, either you can write the variable with Write-Host or slightly more advanced, you can use the debug mode to see exactly what your variables contain.
Hello awesome community :)
I have a list containing a bunch of SKU's. All the filenames of the files, that I need to copy to a new location, starts with the corresponding SKU like so
B6BC004-022_10_300_f.jpg
In this case "B6BC004" is the SKU and my txt list contains "B6BC004" along with many other SKU's.
Somewhere in the code below I know I have to define that it should search for files beginning with the SKU's from the txt file but I have no idea how to define it.
Get-Content .\photostocopy.txt | Foreach-Object { copy-item -Path $_ -Destination "Z:\Photosdestination\"}
Thanks in advance :)
If all files start with one of the SKU's, followed by a dash like in your example, this should work:
$sourceFolder = 'ENTER THE PATH WHERE THE FILES TO COPY ARE'
$destination = 'Z:\Photosdestination'
# get an array of all SKU's
$sku = Get-Content .\photostocopy.txt | Select-Object -Unique
# loop through the list of files in the source folder and copy all that have a name beginning with one of the SKU's
Get-ChildItem -Path $sourceFolder -File -Recurse |
Where-Object { $sku -contains ($_.Name -split '\s*-')[0] } |
ForEach-Object { $_ | Copy-Item -Destination $destination }
I haven't tested this so please proceed with caution!
What is does it loops through all the items in your photostocopy.txt file, searches the $source location for a file(s) with a name like the current item from your file. It then checks if any were found before outputting something to the console and possibly moving the file(s).
$source = '#PATH_TO_SOURCE'
$destination = '#PATH_TO_DESTINATION'
$photosToCopy = Get-Content -Path '#PATH_TO_TXT_FILE'
$photosToCopy | ForEach-Object{
$filesToCopy = Get-ChildItem -Path $source -File | Where-Object {$_.Name -like "$_*"}
if ($fileToCopy.Count -le 0){
Write-Host "No files could be found for: " $_
}else{
$filesToCopy | ForEach-Object{
Write-Host "Moving: " $_.Name
Copy-Item -Path $_.FullName -Destination $destination
}
}
}
Let me know how if this helps you :)
I need to recursively remove all empty folders for a specific folder in PowerShell (checking folder and sub-folder at any level).
At the moment I am using this script with no success.
Could you please tell me how to fix it?
$tdc='C:\a\c\d\'
$a = Get-ChildItem $tdc -recurse | Where-Object {$_.PSIsContainer -eq $True}
$a | Where-Object {$_.GetFiles().Count -eq 0} | Select-Object FullName
I am using PowerShell on Windows 8.1 version.
You need to keep a few key things in mind when looking at a problem like this:
Get-ChildItem -Recurse performs head recursion, meaning it returns folders as soon as it finds them when walking through a tree. Since you want to remove empty folders, and also remove their parent if they are empty after you remove the empty folders, you need to use tail recursion instead, which processes the folders from the deepest child up to the root. By using tail recursion, there will be no need for repeated calls to the code that removes the empty folders -- one call will do it all for you.
Get-ChildItem does not return hidden files or folders by default. As a result you need to take extra steps to ensure that you don't remove folders that appear empty but that contain hidden files or folders. Get-Item and Get-ChildItem both have a -Force parameter which can be used to retrieve hidden files or folders as well as visible files or folders.
With those points in mind, here is a solution that uses tail recursion and that properly tracks hidden files or folders, making sure to remove hidden folders if they are empty and also making sure to keep folders that may contain one or more hidden files.
First this is the script block (anonymous function) that does the job:
# A script block (anonymous function) that will remove empty folders
# under a root folder, using tail-recursion to ensure that it only
# walks the folder tree once. -Force is used to be able to process
# hidden files/folders as well.
$tailRecursion = {
param(
$Path
)
foreach ($childDirectory in Get-ChildItem -Force -LiteralPath $Path -Directory) {
& $tailRecursion -Path $childDirectory.FullName
}
$currentChildren = Get-ChildItem -Force -LiteralPath $Path
$isEmpty = $currentChildren -eq $null
if ($isEmpty) {
Write-Verbose "Removing empty folder at path '${Path}'." -Verbose
Remove-Item -Force -LiteralPath $Path
}
}
If you want to test it here's code that will create interesting test data (make sure you don't already have a folder c:\a because it will be deleted):
# This creates some test data under C:\a (make sure this is not
# a directory you care about, because this will remove it if it
# exists). This test data contains a directory that is hidden
# that should be removed as well as a file that is hidden in a
# directory that should not be removed.
Remove-Item -Force -Path C:\a -Recurse
New-Item -Force -Path C:\a\b\c\d -ItemType Directory > $null
$hiddenFolder = Get-Item -Force -LiteralPath C:\a\b\c
$hiddenFolder.Attributes = $hiddenFolder.Attributes -bor [System.IO.FileAttributes]::Hidden
New-Item -Force -Path C:\a\b\e -ItemType Directory > $null
New-Item -Force -Path C:\a\f -ItemType Directory > $null
New-Item -Force -Path C:\a\f\g -ItemType Directory > $null
New-Item -Force -Path C:\a\f\h -ItemType Directory > $null
Out-File -Force -FilePath C:\a\f\test.txt -InputObject 'Dummy file'
Out-File -Force -FilePath C:\a\f\h\hidden.txt -InputObject 'Hidden file'
$hiddenFile = Get-Item -Force -LiteralPath C:\a\f\h\hidden.txt
$hiddenFile.Attributes = $hiddenFile.Attributes -bor [System.IO.FileAttributes]::Hidden
Here's how you use it. Note that this will remove the top folder (the C:\a folder in this example, which gets created if you generated the test data using the script above) if that folder winds up being empty after deleting all empty folders under it.
& $tailRecursion -Path 'C:\a'
You can use this:
$tdc="C:\a\c\d"
$dirs = gci $tdc -directory -recurse | Where { (gci $_.fullName).count -eq 0 } | select -expandproperty FullName
$dirs | Foreach-Object { Remove-Item $_ }
$dirs will be an array of empty directories returned from the Get-ChildItem command after filtering. You can then loop over it to remove the items.
Update
If you want to remove directories that contain empty directories, you just need to keep running the script until they're all gone. You can loop until $dirs is empty:
$tdc="C:\a\c\d"
do {
$dirs = gci $tdc -directory -recurse | Where { (gci $_.fullName).count -eq 0 } | select -expandproperty FullName
$dirs | Foreach-Object { Remove-Item $_ }
} while ($dirs.count -gt 0)
If you want to ensure that hidden files and folders will also be removed, include the -Force flag:
do {
$dirs = gci $tdc -directory -recurse | Where { (gci $_.fullName -Force).count -eq 0 } | select -expandproperty FullName
$dirs | Foreach-Object { Remove-Item $_ }
} while ($dirs.count -gt 0)
Get-ChildItem $tdc -Recurse -Force -Directory |
Sort-Object -Property FullName -Descending |
Where-Object { $($_ | Get-ChildItem -Force | Select-Object -First 1).Count -eq 0 } |
Remove-Item -Verbose
The only novel contribution here is using Sort-Object to reverse sort by the directory's FullName. This will ensure that we always process children before we process parents (i.e., "tail recursion" as described by Kirk Munro's answer). That makes it recursively remove empty folders.
Off hand, I'm not sure if the Select-Object -First 1 will meaningfully improve performance or not, but it may.
Just figured I would contribute to the already long list of answers here.
Many of the answers have quirks to them, like needing to run more than once. Others are overly complex for the average user (like using tail recursion to prevent duplicate scans, etc).
Here is a very simple one-liner that I've been using for years, and works great...
It does not account for hidden files/folders, but you can fix that by adding -Force to the Get-ChildItem command
This is the long, fully qualified cmdlet name version:
Get-ChildItem -Recurse -Directory | ? { -Not ($_.EnumerateFiles('*',1) | Select-Object -First 1) } | Remove-Item -Recurse
So basically...here's how it goes:
Get-ChildItem -Recurse -Directory - Start scanning recursively looking for directories
$_.EnumerateFiles('*',1) - For each directory...Enumerate the files
EnumerateFiles will output its findings as it goes, GetFiles will output when it is done....at least, that's how it is supposed to work in .NET...for some reason in PowerShell GetFiles starts spitting out immediately. But I still use EnumerateFiles because in testing it was reliably faster.
('*',1) means find ALL files recursively.
| Select-Object -First 1 - Stop at the first file found
This was difficult to test how much it helped. In some cases it helped tremendously, other times it didn't help at all, and in some cases it slowed it down by a small amount. So I really don't know. I guess this is optional.
| Remove-Item -Recurse - Remove the directory, recursively (ensures directories that contain empty sub directories gets removed)
If you're counting characters, this could be shortened to:
ls -s -ad | ? { -Not ($_.EnumerateFiles('*',1) | select -First 1) } | rm -Recurse
-s - alias for -Recurse
-ad - alias for -Directory
If you really don't care about performance because you don't have that many files....even more so to:
ls -s -ad | ? {!($_.GetFiles('*',1))} | rm -Recurse
Side note:
While playing around with this, I started testing various versions with Measure-Command against a server with millions of files and thousands of directories.
This is faster than the command I've been using (above):
(gi .).EnumerateDirectories('*',1) | ? {-Not $_.EnumerateFiles('*',1) } | rm -Recurse
ls c:\temp -rec |%{ if ($_.PSIsContainer -eq $True) {if ( (ls $_.fullname -rec | measure |select -expand count ) -eq "0" ){ ri $_.fullname -whatif} } }
Assuming you're inside the parent folder of interest
gci . -Recurse -Directory | % { if(!(gci -Path $_.FullName)) {ri -Force -Recurse $_.FullName} }
For your case with $tdc it'll be
gci $tdc -Recurse -Directory | % { if(!(gci -Path $_.FullName)) {ri -Force -Recurse $_.FullName} }
If you just want to make sure, that you delete only folders that may contain subfolders but no files within itself and its subfolders, this may be an easier an quicker way.
$Empty = Get-ChildItem $Folder -Directory -Recurse |
Where-Object {(Get-ChildItem $_.FullName -File -Recurse -Force).Count -eq 0}
Foreach ($Dir in $Empty)
{
if (test-path $Dir.FullName)
{Remove-Item -LiteralPath $Dir.FullName -recurse -force}
}
Recursively removing empty subdirectories can also be accomplished using a "For Loop".
Before we start, let's make some subdirectories & text files to work with in $HOME\Desktop\Test
MD $HOME\Desktop\Test\0\1\2\3\4\5
MD $HOME\Desktop\Test\A\B\C\D\E\F
MD $HOME\Desktop\Test\A\B\C\DD\EE\FF
MD $HOME\Desktop\Test\Q\W\E\R\T\Y
MD $HOME\Desktop\Test\Q\W\E\RR
"Hello World" > $HOME\Desktop\Test\0\1\Text1.txt
"Hello World" > $HOME\Desktop\Test\A\B\C\D\E\Text2.txt
"Hello World" > $HOME\Desktop\Test\A\B\C\DD\Text3.txt
"Hello World" > $HOME\Desktop\Test\Q\W\E\RR\Text4.txt
First, store the following Script Block in the variable $SB. The variable can be called later using the &SB command. The &SB command will output a list of empty subdirectories contained in $HOME\Desktop\Test
$SB = {
Get-ChildItem $HOME\Desktop\Test -Directory -Recurse |
Where-Object {(Get-ChildItem $_.FullName -Force).Count -eq 0}
}
NOTE: The -Force parameter is very important. It makes sure that directories which contain hidden files and subdirectories, but are otherwise empty, are not deleted in the "For Loop".
Now use a "For Loop" to recursively remove empty subdirectories in $HOME\Desktop\Test
For ($Empty = &$SB ; $Empty -ne $null ; $Empty = &$SB) {Remove-Item (&$SB).FullName}
Tested as working on PowerShell 4.0

Something like this works for me. The script delete empty folders and folders containing only folder (no files, no hidden files).
$items = gci -LiteralPath E:\ -Directory -Recurse
$dirs = [System.Collections.Generic.HashSet[string]]::new([string[]]($items |% FullName))

$remove | rm
$dirs.ExceptWith( [string[]]$remove )
}
else {
break
}
}
I wouldn't take the comments/1st post to heart unless you also want to delete files that are nested more than one folder deep. You are going to end up deleting directories that may contain directories that may contain files. This is better:
$FP= "C:\Temp\"
$dirs= Get-Childitem -LiteralPath $FP -directory -recurse
$Empty= $dirs | Where-Object {$_.GetFiles().Count -eq 0 **-and** $_.GetDirectories().Count -eq 0} |
Select-Object FullName
The above checks to make sure the directory is in fact empty whereas the OP only checks to make sure there are no files. That in turn would result in files nexted a few folders deep also being deleted.
You may need to run the above a few times as it won't delete Dirs that have nested Dirs. So it only deletes the deepest level. So loop it until they're all gone.
Something else I do not do is use the -force parameter. That is by design. If in fact remove-item hits a dir that is not empty you want to be prompted as an additional safety.
$files = Get-ChildItem -Path c:\temp -Recurse -Force | where psiscontainer ; [array]::reverse($files)
[Array]::reverse($files) will reverse your items, so you get the lowest files in hierarchy first.
I use this to manipulate filenames that have too long filepaths, before I delete them.
This is a simple approach
dir -Directory | ? { (dir $_).Count -eq 0 } | Remove-Item
This will remove up all empty folders in the specified directory $tdc.
It is also a lot faster since there's no need for multiple runs.
$tdc = "x:\myfolder" # Specify the root folder
gci $tdc -Directory -Recurse `
| Sort-Object { $_.FullName.Length } -Descending `
| ? { $_.GetFiles().Count -eq 0 } `
| % {
if ($_.GetDirectories().Count -eq 0) {
Write-Host " Removing $($_.FullName)"
$_.Delete()
}
}
