Answer 1

The Remove-Item command has a known issue.

Try this instead:

if (Test-Path $OUT) 
{ 
    # if exists: empty contents and reuse the directory itself
    Get-ChildItem $OUT -Recurse | Remove-Item -Recurse
}
else
{
    # else: create
    New-Item -ItemType Directory -Path $OUT
}

Note:

• The Get-ChildItem command only finds non-hidden files and subdirectories, so emptying out the target directory may not be complete; to include hidden items too, add -Force.

• Similarly, add -Force to -RemoveItem to force removal of files that have the read-only attribute set.

  • Without -Force, emptying may again be incomplete, but you'll get non-terminating errors in this case; if you want to treat them as terminating errors, add -ErrorAction Stop too.
