Orphan files

ProjectSend includes a page (Files -> Find orphan files) where you can view and import or delete any file that is present in the uploads folder but does not exist in the database.
This is specially useful if you, for example, upload certain files via FTP way to your server directly and want to have control over importing just a subset of them.
Once a file is imported, it can be edited the same way as any file that was directly uploaded via the UI.
The same file types restrictions from regular uploads also apply to orphan files.
