I have this directory with thousands of folders n it going back to 2011, with files in them named such as "file_TfnK9c"

What are they, I am thinking of backing up then deleting most of the real old ones.

I am guessing the hold order info, but as most of my customers check out as guest and we hold all order info locally anyway going back 10 years I am thinking of deleting them.

Any major problems if I delete them

Do you have any product options with the File type? Looks like this directory is used for these files
