I have a file directory that contains many folders within it. Inside each of these sub-folders, I have a variety of files. I would like to go through each file, rename some of the items, and add extensions to some of them. I am using Powershell to do this.
I have file names with "." that all need to be replaced with "_" for example, "wrfprs_d02.03" should be "wrfprs_d02_03". I was able to successfully do that in one folder with the following code:
dir | rename-item -NewName {$_.name -replace "wrfprs_d02.","wrfprs_d02_"}
After, I make those replacements, I want to add .grb extensions on to some of the files, which all happen to start with "w", and I was able to do that within one folder with:
Get-ChildItem | Where-Object {$_.Name -match "^[w]"} | ren -new {$_.name + ".grb"}
When I step back from one folder and try to do it iteratively within many folders, my code doesn't work. I am in a directory called "Z:\Windows.Documents\My Documents\Test_data\extracted" which contains all my sub-folders that I want to iterate over. I am using the following code:
$fileDirectory = "Z:\Windows.Documents\My Documents\Test_data\extracted"
foreach($file in Get-ChildItem $fileDirectory)
{
dir | rename-item -NewName {$_.name -replace "wrfprs_d02.","wrfprs_d02_"}
Get-ChildItem | Where-Object {$_.Name -match "^[w]"} | ren -new {$_.name + ".grb"}
}
Any ideas on what my problem is?
because you $_ is replaced into loop when you use pipe. I propose you a new code:
$fileDirectory = "Z:\Windows.Documents\My Documents\Test_data\extracted"
Get-ChildItem $fileDirectory -recurse -file -filter "*.*" |
%{
#replace . by _
$NewName=$_.Name.Replace(".", "_")
#add extension grb if name start by w
if ($NewName -like "w*") {$NewName="$NewName.grb"}
#Add path file
$NewName=Join-Path -Path $_.directory -ChildPath $NewName
#$NewName
#rename
Rename-Item $_.FullName $NewName
}
Not sure what error you were getting, but using rename-item can be finicky. Or at least so in my experience.
I used the follow without issue. My files names were different so I replaced all periods with underscores. If the file starts with "W" then it changed the extension for that file.
$FilePath = Get-ChildItem "Z:\Windows.Documents\My Documents\Test_data\extracted" -Recurse -File
foreach ($file in $FilePath)
{
$newName = $file.Basename.replace(".","_")
$New = $newName + $file.Extension
if($file.Name -match "^[w]")
{
Rename-Item $file.FullName -NewName "$($New).grb"
}
else
{
Rename-Item $file.FullName -NewName $New
}
}
Hope that helps.

I am trying to rename files in subfolders in a certain pattern, but I am stuck.
The situation is as follows: I have multiple folders which are sometimes named as the target filename depending on the length, but the name does not really matter.
In each folder are always 2 files: the Target-File with a random name and the correct extension, and the Source-File which is always the correct BaseName with a txt-extension.
For example:
Folder1\7393028473.docx
Folder1\January.txt
Folder2\9373930843.pdf
Folder2\February.txt
My goal is to rename every not-txt-file with the Basename of the txt-file. Executed, it should be like:
Folder1\January.docx
Folder1\January.txt
Folder2\February.pdf
Folder2\February.txt
With gci I was able to create both lists but didn't find a good way for the renaming.
$SourceName = gci -File -Recurse | Where {$_.Extension -ne ".txt"}
$TargetName = gci -File -Recurse | Where {$_.Extension -eq ".txt"}
I did also try to use gci for renaming, but was not able to tell it to use the newname based on the txt-file:
gci -File -Recurse | Where {$_.Extension -ne ".txt"} | Rename-Item -NewName {$_.extension -eq ".txt"}
This only renamed the .docx-file to "FALSE" because the filename already exists.
What I did not try (but would be ok) is to not only rename the file, but also move it to the parent directory.
This is one way to do it but it would fail as soon as there are 2 or more files with a different extension than .txt but having the same extension. It would also fail as soon as one folder has more than one .txt file.
# Get all folders under 'TargetDirectory'
Get-ChildItem TargetDirectory -Directory -Recurse | ForEach-Object {
# For each sub-folder, get their files
$childs = $_.EnumerateFiles()
# Filter and split the child files by their extension
$txt, $notTxt = $childs.Where({ $_.Extension -eq '.txt' }, 'Split')
# Use the BaseName of the '.txt' File but the Extension of
# the file being renamed
$notTxt | Rename-Item -NewName { $txt.BaseName + $_.Extension }
}
Thanks for your reply and sorry for my late reply.
I tried your code but its not working correctly:
The NewName is created correctly, but the problem is the rename-function or rather the notTxt list because it only contains the item itself but not hte full path.
When I copy the file which should be renamed into the parent-directory your code does work in the file in the parent-directory.
There was another answer which apperntly was deleted but did work.
I also tried a foreach-loop in one of my tries but didn't get the NewName to work.
I don't know why, but I didn't consider creating the NewName with a variable, which was done in the deleted answer:
$folders = gci -Directory -Recurse
foreach ($folder in $folders) {
$targetFile = gci $folder | Where {$_.Extension -ne ".txt"}
$sourceFile = gci $folder | Where {$_.Extension -eq ".txt"}
$newName = $sourceFile.BaseName + $targetFile.Extension
Rename-Item $targetFile.FullName $newName
}
Of course you can try and get your code to work, but I can make do with this code.
Thank you very much for your help.
I have a directory c:\test with files 0001 test.pdf, 0002ssssit.pdf, 0003llllllllllll.pdf
My goal is to use PS to use a a loop to go through the directory and rename the files to:
0001.pdf
0002.pdf
0003.pdf
I keep getting path errors
$List = get-childitem "C:\test"
$List |Format-Wide -Column 1 -property name
ForEach($File In $List)
{
$First4 = $File.name.substring(0,4)
Rename-Item -newname $First4".pdf"
}
You need to pass the original file path to Rename-Item, otherwise it won't know what to rename!
Either:
$file | Rename-Item -NewName "${First4}.pdf"
or
Rename-Item -LiteralPath $file.FullName -NewName "${First4}.pdf"
inside the foreach body.
You could also use a single pipeline to accomplish the same (-NewName supports pipeline binding):
$List | Rename-Item -NewName { $_.Name.Substring(0,4) + $_.Extension }
try Something like this:
Get-ChildItem "c:\temp" -file "*.pdf" |
where Name -match "^[0-9]{4}" |
rename-item -NewName {"{0}{1}" -f $_.BaseName.Substring(0, 4), $_.Extension}
newbie here. I am trying to write a PowerShell script to:
loop through all files in directory
List item
Get all .pdf files ONLY
Rename them-the file names are long - over 30 chars
-They contain 2 numbers which I need to extract
-Example:
Cumulative Update 11 for Microsoft Dynamics NAV 2018 (Build 25480).pdf ->
RESULT : = 18CU11.pdf
I tried examples from bunch of sites and I can't seem to even loop successfully.
Either get an error - that path doesn't exist or that can't rename files as somehow loop gets a filepath and that I can't rename
Get-ChildItem "C:\Users\******\Desktop\PowerShell Practice" -Filter *.pdf | #create list of files
ForEach-Object{
$oldname = $_.FullName;
$newname = $_.FullName.Remove(0,17);
#$newname = $_.FullName.Insert(0,"CU")
Rename-Item $oldname $newname;
$oldname;
$newname; #for testing
}
That's just latest attempt, but any other ways of doing it will be fine - as long as it does the job.
Try this logic:
[string]$rootPathForFiles = Join-Path -Path $env:USERPROFILE -ChildPath 'Desktop\PowerShell Practice'
[string[]]$listOfFilesToRename = Get-ChildItem -Path $rootPathForFiles -Filter '*.PDF' | Select-Object -ExpandProperty FullName
$listOfFilesToRename | ForEach-Object {
#get the filename wihtout the directory
[string]$newName = Split-Path -Path $_ -Leaf
#use regex replace to apply the new format
$newName = $newName -replace '^Cumulative Update (\d+) .*NAV 20(\d+).*$', '$2CU$1.pdf' # Assumes a certain format; if the update doesn't match this expectation the original filename is maintained
#Perform the rename
Write-Verbose "Renaming '$_' to '$newName'" -Verbose #added the verbose switch here so you'll see the output without worrying about the verbose preference
Rename-Item -Path $_ -NewName $newName
}
Check the Help for Rename-Item. The Parameter -NewName requires the name of the file only, not the full path.
Try out this:
Get-ChildItem "C:\Users\******\Desktop\PowerShell Practice-Filter" -Filter *.pdf | #create list of files
ForEach-Object{
$oldname = $_.FullName
$newname = $_.Name.Remove(0,17)
Rename-Item -Path $oldname -NewName $newname
$oldname
$newname #for testing
}
Please try this
Get-ChildItem -Path "C:\Users\******\Desktop\PowerShell Practice-Filter" -Filter *.pdf | Rename-Item -NewName $newname
I have to go through many levels of child folders and remove special characters that are invalid in SharePoint, mainly '#&'
I have scoured the internet trying different commands; rename-item/move-item, variations of the two, all to no avail. The closest i've gotten is using:
Get-ChildItem -Recurse | Rename-Item -NewName {$_.Name -replace'[!##&]','_'}
but i keep getting this error: Rename-item: Source and destination path must be different.
Could someone point me in the right direction?
Regards
That error only happens when you attempt to rename a directory to the same NewName as the current name, you can safely ignore it.
Add -ErrorAction SilentlyContinue to silently suppress the error message:
Get-ChildItem -Recurse | Rename-Item -NewName {$_.Name -replace'[!##&]','_'} -ErrorAction SilentlyContinue
You need to filter out the files that you're not planning to rename:
Get-ChildItem -Recurse |
Where-Object { $_.Name -match '[!##&]' } |
Rename-Item -NewName {$_.Name -replace '[!##&]','_'}
something like this may work
dir -Recurse -File | ? basename -Match '[!##&]' | % {
# if the file.txt already exists, rename it to file-1.txt and so on
$num = 1
$base = $_.basename -replace'[!##&]', '_'
$ext = $_.extension
$destdir = Split-Path $_.FullName
$newname = Join-Path $destdir "$base$ext"
while (Test-Path $newname) {
$newname = Join-Path $destdir "$base-$num$ext"
$num++
}
ren $_.fullname $newname
}
I am trying to remove blank spaces from many file names using PowerShell 3.0. Here is the code that I am working with:
$Files = Get-ChildItem -Path "C:\PowershellTests\With_Space"
Copy-Item $Files.FullName -Destination C:\PowershellTests\Without_Space
Set-Location -Path C:\PowershellTests\Without_Space
Get-ChildItem *.txt | Rename-Item -NewName { $_.Name -replace ' ','' }
For example: the With_Space directory has these files:
Cable Report 3413109.pdf
Control List 3.txt
Test Result Phase 2.doc
The Without_Space directory will need the above file name to be:
CableReport3413109.pdf
ControlList3.txt
TestResultPhase 2.doc
Currently, the script shows no error but it only copies the source files to the destination folder, but doesn't remove the spaces in file names.
Your code should work just fine, but since Get-ChildItem *.txt lists only .txt files the last statement should remove the spaces from just the text files, giving you a result like this:
Cable Report 3413109.pdf
ControlList3.txt
Test Result Phase 2.doc
This should remove spaces from the names of all files in the folder:
Get-ChildItem -File | Rename-Item -NewName { $_.Name -replace ' ','' }
Prior to PowerShell v3 use this to restrict processing to just files:
Get-ChildItem | Where-Object { -not $_.PSIsContainer } |
Rename-Item -NewName { $_.Name -replace ' ','' }
something like this could work
$source = 'C:\temp\new'
$dest = 'C:\temp\new1'
Get-ChildItem $source | % {copy $_.FullName $(join-path $dest ($_.name -replace ' '))}
I think your script should almost work, except $_ isn't going to be defined as anything. By using the for-each cmdlet (%), you assign it and then can use it.
Get-ChildItem *.txt | %{Rename-Item -NewName ( $_.Name -replace ' ','' )}
EDIT:
That interpretation was totally wrong. Some people seem to have found it useful, but as soon as you have something being piped, it appears that $_ references the object currently in the pipe. My bad.
