Files are not stored in a simple directory on a server, but distributed across storage servers using a proprietary platform. A file on a server has just a number, so it would not be possible to know what software to open that file with, or to differentiate your file from any other user's file without referring to the main database which holds this information.

The web interface does all this for you, but since we cannot login as you (because we don't store your password only a checksum of it) it would be a laborious job for anyone here to look at your files as it would be necessary to manually convert each one into it's id number, find which server that id is stored on, then retrieve it from the server and rename it.
