Windows 10, Rename all *.jpg files in all subdirectories, with number starting from 1

Question

I want a solution for the same problem, but in Windows 10. Recursively rename .jpg files in all subdirectories

I tried with following powershell command, Get-ChildItem -Recurse -Include *.jpg | % { Rename-Item $_ -NewName ('{0:D1}.jpg' -f $i++)}

but it renames the files in sequential order without resetting the index to 1 in every sub folder.

Answer 1

I think you need two separate Get-ChildItem cmdlets for this. The first will gather all subdirectories and when looping though that, the second will gather the files in each directory:

Get-ChildItem -Path 'X:\RootFolder\where\the\files\are' -Recurse -Directory | ForEach-Object {
    $count = 1   # reset the counter for this subdir to 1
    Get-ChildItem -Path $_.FullName -Filter '*.jpg' -File | ForEach-Object {
        $_ | Rename-Item -NewName ('{0:D1}.jpg' -f $count++) -WhatIf
    }
}

Remove the -WhatIf if you are satisfied with the results shown in the console.

^{P.S. the title says *.png, but your code deals with *.jpg. Doesn't matter, as long as you set your filter to the correct extension and adjust the new name in the code accordingly}
