Hi all,

I need to make multiple files in one folder (C:\Users\Desktop\BMS\Siemens Data) change from being the Type of file : File to a Type of file: Text Document (.txt). How do I do that using powershell?

    If I understand you correctly, this is very common. Take off the -whatif if it looks right. Added parentheses so the first part finishes before the second part. 

    (get-childitem -file) | rename-item -newname { $_.name + '.txt' } -whatif

What if: Performing the operation "Rename File" on target "Item: C:\users\js\foo Destination: C:\users\js\foo.txt".
