I have this code to mass rename all the .mkv & .mp4 files in the specific directory of my choosing:
$i = 0; Get-ChildItem "$env:UserprofileVideosMovie_Best_Clips" -Filter "vlc-record-2024*.mp4" -Recurse | %{Rename-Item $_.FullName -NewName ($_.Directory.Name+'_'+'_{0:D4}.mp4' -f $i++)};
$i = 0; Get-ChildItem "$env:UserprofileVideosMovie_Best_Clips" -Filter "vlc-record-2024*.mkv" -Recurse | %{Rename-Item $_.FullName -NewName ($_.Directory.Name+'_'+'_{0:D4}.mkv' -f $i++)};
There are multiple directories inside $env:UserprofileVideosMovie_Best_Clips in those folders are the files that match pattern vlc-record-2024*.mp4 or vlc-record-2024*.mkv.
Now I want to, without making any major code altering changes, include a check for whether a file with same name as the name made by iterator exists or not in the given directory, either before or inside Rename-Item line.
If such file already exists then just do continue like behaviour and increment the iterator and subsequently give a fresh name to file, to avoid rename-item errors.
So for example if file with name “MOVIENAME 2024 ENGLISH 1080P.mkv__0002.mp4” already exists(in the same directory as the existing “vlc-record-2024” file* that’s to be renamed) then just rename the file in question with “MOVIENAME 2024 ENGLISH 1080P.mkv__0003.mp4” and like that on each and every iteration.
I saw this answer but the answerer has made the code too long, I want to do it in shortest way possible, but can’t wrap my head around about how to achieve it, any help is appreciated.
You could probably accomplish this in a single Get-ChildItem call using a hashtable that contains the index for each extension. There is also no need for a ForEach-Object loop if you use a delay-bind scriptblock.
$i = @{ '.mkv' = 0; '.mp4' = 0 }
$getChildItemSplat = @{
Include = 'vlc-record-2024*.mkv', 'vlc-record-2024*.mp4'
Recurse = $true
Path = "$env:UserprofileVideosMovie_Best_Clips"
}
Get-ChildItem @getChildItemSplat | Rename-Item -NewName {
while ($true) {
$name = '{0}_{1:D4}{2}' -f $_.Directory.Name, $i[$_.Extension]++, $_.Extension
if (-not (Test-Path (Join-Path $_.DirectoryName $name))) {
break
}
}
$name
}

An if the incremented name does also allready exist, and the next, and the one after it…………? While loop!
Get-ChildItem "C:UsersYourTargetDir" -Filter "vlc-record-2024*.mp4" -Recurse | ForEach-Object {
$noNewNameFound=$true
while($noNewNameFound){
$newName= $_.Directory.Name+'_'+'_{0:D4}.mkv' -f $i
if(test-path "$($_.parent)$newname"){$i++}
else{Rename-Item $_.FullName -NewName $newName ; $noNewNameFound=$false; $i++}
}
}
