These commands show the value of using a provider-specific filter in Windows PowerShell commands.

The first command measures the time it takes to process a recursive Get-ChildItem command that uses the Path parameter to get only .txt files in the C:\Windows directory and its subdirectories.

The second command measures the time it takes to process a recursive Get-ChildItem command that uses the provider-specific Filter parameter.
