Powershell - IO.Directory - Find file types in all subdirectories

Question

I ran across this code in another post that almost does what I need, but can\'t figure out how to modify it to look for specific file types, i.e. *.bak, .txt, etc. I\'m

This will loop through each extension searching for all files in the root and sub-directories. Ensure you have the correct privileges on all the directories especially when you're running from C:\ as the root.

$Extensions = @(".bak",".csv",".txt")

Foreach ( $Extension in $Extensions )
{
   [System.IO.Directory]::EnumerateFiles("C:\","*$Extension","AllDirectories")
}

This method will only work with Powershell running .Net 4.0 or higher. To check and update the version of .Net:

$PSVersionTable

Name                           Value
----                           -----
CLRVersion                     2.0.50727.4971
BuildVersion                   6.1.7600.16385
PSVersion                      2.0
WSManStackVersion              2.0
PSCompatibleVersions           {1.0, 2.0}
SerializationVersion           1.1.0.1
PSRemotingProtocolVersion      2.1

The CLRVersion value is the .net version.

Update the config file as follows:

$Config = @"


    
        
        
    

"@

$Config > $PSHOME\Powershell.exe.config

Restart the Powershell session and verify the CLRVersion value in the $PSVersionTable variable.
