Cyber-D's Autodelete can delete old files in a folder (and subfolders) you selected. Simply select the folder you wish to clean (downloads for example), set the rules (older than 30 days since created) and how to delete (move, recycle, secure delete). The cleanup is done on system startup only so it does not stay open in the background or you can run the cleanup manually. Log files are created per clean session and filters can be applied. Cleaning status window, run on startup and log files can be disabled if you wish.
