When you use Get-ChildItem to get a list of files, you may have noticed that the -Filter parameter occasionally returns more files than you’ve expected.
Here is an example of this. This line does not just return files with a ".ps1" extension, but also files with the ".ps1xml" file extension:
Get-ChildItem -Path C:\windows -Recurse -ErrorAction SilentlyContinue -Filter *.ps1
To limit the result set to just the extension you are after, add a cmdlet filter to refine the results:
Get-ChildItem -Path C:\windows -Recurse -ErrorAction SilentlyContinue -Filter *.ps1 | Where-Object { $_.Extension -eq '.ps1' }
This will return files with the specified extension only.
