App to automatically delete old files

[rfc3501]

I searched Play Store for several hours, without much luck. Anyone knows of an app that can be set up to execute on its own, at regular intervals, and automatically delete anything in the Downloads directory that's older than the given number of days, that's all.

Perhaps SD Maid?

According to the dev website, it can schedule tasks:

The scheduler allows you to automate running the different cleaning tools. The execution time may differ by +/- 10 minutes on some devices to save battery. The system may bundle several alarms and wakeup calls and not trigger each one immediatly.......

Edit: hmm, reading some more there, I'm not sure if it can delete your downloads contents.
