Hi there, I have trouble running the script. Is there an example how to make the call?
Powershell throws the error:

Select-String: The File C:\myFolder can´t be read: The access to the path "C:\myFolder" is permitted.
In C:\myFolder\DeleteExcludedFiles.ps2: 36 Char:26

Thanks for sharing this script. Let me suggest an improvement for the exclusion regex. Terminate ".user" and ".*proj" with a $. Otherwise one can get:

ForEach-Object : Cannot bind argument to parameter 'ReferenceObject' because it is null.

In other words, L50 should read:

| ? { $_ -notmatch "\\obj\\|\\bin\\|\\logs\\|\.user$|\.*proj$|App_Configuration\\|App_Data\\" }
