  Windows PowerShell Get a list of items in "Desktop" or "Documents" Creating a function. function testFunc($inarg){ cd ~ if($inarg -eq "Desktop"){cd "Desktop";} elseif($inarg -eq "Documents"){cd "Documents";} $items= ls; return $items; } Command line to print(echo) items(files and folders) in "Desktop". $items=Invoke-Command -ScriptBlock $function:testFunc -ArgumentList "Desktop";echo $items; Command line to print(echo) items(files and folders) in "Documents". $items2=Invoke-Command -ScriptBlock $function:testFunc -ArgumentList "Documents";echo $items2;

Right click "Start" and select Windows PowerShell. In the PowerShell, use "cd" to move to the directory(folder). e.g. cd C:\Users\[User Login]\Documents\test\ to move to "test" folder in your Documents folder. To rename files in this current folder, use PowerShell command like below. Get-ChildItem "*.jpg" | Sort Name | % { $i = 1} { $Newname = "rename_image" + $i.ToString("000") + $_.extension; Rename-item $_ $Newname; $i++ } This renames all jpg files to "renamed_image###".jpg If there are three jpg files, the files will be renamed_image001.jpg renamed_image002.jpg renamed_image003.jpg
