 “Windows only: Free application Auto Delete monitors any user-specified folder and deletes files older than a set amount of time, from 1 day to 1 year.

Once deleted, files can either be sent to the Recycle Bin or permanently deleted.

There isn't much else Auto Delete can do beyond that, but it's one of those dead simple tools that does exactly what it says without much fuss, which we always like.

On the other hand, if you're looking for a more robust version of Auto Delete—including options to move, rename, copy, or delete files based on multiple conditions—you might consider giving our very own automated file management tool Belvedere a try. Auto Delete is a free download, Windows only.”
