Deleting files

[smartglass]

Hi:
I am trying to write a little utility that deletes all pdf files in a given directory over 14 days old.
remove() can delete specified files; but does anybody know how to delete a range, and over a given age?
Thanks!

You will need to look at FindFirst() and FindNext(). Look at thread101-525513 for starters.
