How can I automatically delete files by date and/or time?

[michwarn]

I easily get lost in the land of computers and often need help. Here is the first question of many that are sure to follow.
I would like set up a folder where the files within are automatically deleted after 30 days. Is this something that can be accomplished through command prompt or other means? (operating system XP) Oh, I will need explicit instructions. I appreciate any help!!

maybe u need to look for software as windows does not have anything like this. be aware that software for this purpose may cost you.

it is prob just as easy to delete files manually
