This is another reason I like Unix-like operating systems...symbolic links. :biggrin1:
My porn collection takes up more than 2TB of the 4.5TB array on my storage server.
I have scenes categorized by site, by performer, etc...so naturally some scenes would go in more than one category. In the Linux world, you just create a link to the file in each category where it belongs...it appears that you've put a new copy in each place, but in reality they're all just pointers to the one real copy of the file.
So a favorite scene with, say, Gianna Michaels might be in all these different directories (folders) on the filesystem:
/Brunettes
/Big Tits
/Naturals
/Creampies
/Brazzers
...but in raw storage terms, there's only one copy of the data actually taking up drive space.
