Hello!

I need to delete files existing in a shared location after 3 months . I can calculate how old each file is and if it is older than 90 days, delete it. However, sometime happends that an old file is copied in the shared location, and let's say one day after I check the files, it says that the files is too old and delete it, but it had just one day in this location. I just want to delete files with more than 90 days in that place, does not matter how old the files is...Do you get it?! Do I explain myself?
Thanks!
