We have in our office an external USB drive used to save folders from several users. Any time that I need to make a backup to the drive, I pass it to the user and he/she will save the needed folders.
I need to find the posibility that the user have only access to the folder he is creating and not the to the others on the drive. I’ve seen several softwares to password protect the folders or even encrypt them, but I would like to know if there is any other option.
