This is just a little linux command line hack for removing all files older than X days (Substitute the X for the number of days):
find /[path]/* -mtime +X -exec rm -rf {} \;
eg “find /var/www/html/* -mtime +3 -exec rm -rf {} \;” to delete all files in the html directory older than 3 days.
Before running this you can also check what will be deleted by running the following:
find /[path]/* -mtime +X -exec ls -la {} \;
