OK, this may seem easy but I figured I would document this just in case it bugs anyone else like it bugged me. It appears that the best way to recursively delete files and directories on Windows XP and Vista is using the "rd /s" command. On previous versions of Windows, e.g., Windows 2000 and Windows 98, you could run the deltree command. The deltree command was obsoleted on Vista and XP. So, if you're ever in a command prompt and want to delete a directory, and all directories and files inside of it, think "rd /s".

Yea.
