Question

I have a Visual Studio solution with several projects. I clean up the bin and obj folders as part of clean up using the following script.

Get-ChildItem -path source -filter obj -recurse | Remove-Item -recurse
Get-ChildItem -path source -filter bin -recurse | Remove-Item -recurse

This works perfectly. However, I have a file-based data folder that has about 600,000 sub folders in it and is located in a folder called FILE_DATA.

The above script takes ages because it goes through all these 600,000 folders.

I need to avoid FILE_DATA folder when I recursively traverse and remove bin and obj folders.

Answer 1

If the FILE_DATA folder is a subfolder of $source (not deeper), try:

$source = "C:\Users\Frode\Desktop\test"
Get-Item -Path $source\* -Exclude "FILE_DATA" | ? {$_.PSIsContainer} | % {
    Get-ChildItem -Path $_.FullName -Filter "obj" -Recurse | Remove-Item -Recurse
    Get-ChildItem -Path $_.FullName -Filter "bin" -Recurse | Remove-Item -Recurse
}
