delete files in specific directory

i have a directory "ABC" with lots of old files and sub directories in it.
the issue now is i want to delete away files which are older than 15 days in "ABC" without deleting the files in the sub directories and without deleting the sub directory.
i tried using find command but it will drill down to the sub directory and delete files.
anyone has got a script to deal with this?
i have zero experience in scripting so lots of help will be appreciated :slight_smile:

See this thread

thanks a million!
