Delete directories

Hello,

Last year I advised my forum users that at the beginning of the year I was going to delete all images and uploaded files because they took up a lot of space.

The problem is that I have also deleted the directories of each user and if they want to enter to re-upload their files can not because their directory does not exist.

Is there a way or code to re-create the directories of all registered users?

Thank you,
