How about the ftp has another folder called Magazines. Then have sub folders, name of each amiga magazine and the contents of disks, cds, page scans and covers taking seperate sub folders.
This would make it a lot quicker to find a certain disk (in magazine floppy folder). Or a cd (in magazine cd folder) etc.
could look into it, may need to inform user folder uploaders of the move. Then what to do with double files, find the ones that are better to keep! This won't gain much ftp space, but will make for finding magazine things quickly and easily.
