Trying to rename bulk files in subfolders, works only in path folder


I am trying to rename all files including "R0" to "r" with the following loop

$files = Get-ChildItem -Path "D:\folder\" -Recurse -File

foreach ($file in $files)



Rename-Item $file $newFileName


For some reason it does not work in subfolders, even first line

Get-ChildItem -Path "D:\folder\" -Recurse -File

finds all the files in the subfolder. Not trying to move the files from their original location

What am I doing wrong? Not super familiar with PS. Thanks :)

You may want to consider filtering your results before performing your rename operation. Right now if there are files that don't have 'R0' in the name, it still gets touched by Rename-Item. Here's how I would approach it:

Get-ChildItem -Path 'D:\folder\' -Recurse -File |
    Where-Object {$_.Name -cmatch 'R0'} |
    Rename-Item -NewName {$_.Name -creplace 'R0', 'r'} -WhatIf

This way only the items that are case sensitive matched get an operation ran against it. You can run this as a test with the -WhatIf switch and if everything looks good, remove it.

You should provide the error message.

I'm guessing your present working directory is 'D:\folder' when you run it? Are you getting a 'does not exist' error for the files not in your present working directory (subfolders)?

Rename-Item wants a path to the file in the -Path parameter, you're passing in the FileInfo object, so you're only providing the filename.


Rename-Item -Path $file.FullName -NewName $newFileName

Wondered it had something to do with path but couldn't figure out the . Fullname for the path. Thanks a ton, worked!

howdy Unqqq,

reddit likes to mangle code formatting, so here's some help on how to post code on reddit ...

[0] single line or in-line code
enclose it in backticks. that's the upper left key on an EN-US keyboard layout. the result looks like this. kinda handy, that. [grin]
[on, use the Inline Code button. it's 4th 5th from the left hidden in the ... ""more" menu & looks like </>.
this does NOT line wrap & does NOT side-scroll on!]

[1] simplest = post it to a text site like or and then post the link here.
please remember to set the file/code type on Pastebin! [grin] otherwise you don't get the nice code colorization.

[2] less simple = use reddit code formatting ...
[on, use the Code Block button. it's 11th 12th one & is just to the left of hidden in the ... "more" menu.]

  • one leading line with ONLY 4 spaces

  • prefix each code line with 4 spaces

  • one trailing line with ONLY 4 spaces

that will give you something like this ...

- one leading line with ONLY 4 spaces    
- prefix each code line with 4 spaces    
- one trailing line with ONLY 4 spaces   

the easiest way to get that is ...

  • add the leading line with only 4 spaces

  • copy the code to the ISE [or your fave editor]

  • select the code

  • tap TAB to indent four spaces

  • re-select the code [not really needed, but it's my habit]

  • paste the code into the reddit text box

  • add the trailing line with only 4 spaces

not complicated, but it is finicky. [grin]

take care,

I am very aware of this. If you read my post carefully, you'll realize that my post has only 4 lines of code excluding { & }'s. Doesn't need much imagination in order to read it without formatting.

howdy Unqqq,

[i took your post as quite hostile. re-thinking it ... i may well be entirely wrong. if so, i apologize. please let me know and i will correct this msg ... ]

well, if you really prefer it, i will try to remember that bizarre preference and try not to nag you. [grin]

your preference ...

$files = Get-ChildItem -Path "D:\folder" -Recurse -File

foreach ($file in $files)



Rename-Item $file $newFileName


done correctly for easier readability ...

$files = Get-ChildItem -Path "D:\folder\" -Recurse -File

foreach ($file in $files)



Rename-Item $file $newFileName


of course, you could try to use proper indentation, but i guess that goes along with your preference for remarkably icky code formatting. [grin]

take care,
