I want to create a private area for users where they can have their files and information. Is there any module for it or some way to develop it?
I’m not aware of an existing module but this is the kind of thing you can build relatively easily with SilverStripe. If you describe in detail exactly what you want to build I can try to give you some tips (“have their files and information” isn’t much to go on ).
Are you looking for a front end module or something for CMS users?
use the ‘canView’ method of the files that linked to different members so that only member ‘owns’ the file can view it.
