Hiding file that must be on computer.

I have another quick question for everyone! I want to hide a file on a users computer that will be deleted after 30 or so days, but the program must have it to run. Kinda like PreviewSoft does with their TimeLock software. Anybody have any ideas?

Thanks again!

SetFileAttributes can be used to make the file hidden.
You also might want to set its name to something like zzzfile
so it falls to the bottom of a sorted list.
