Attachments and document directory

Can projeqtor work with netword directories like "\\servername\foldername$\" (hidden folder) or "\\servername\foldername\"?
I configured a network directory as shown in the example above and neither attachments nor documents are salved in the folder I've configured. However, Projeqtor is able to deal with documents (even as attachments or as documents).
Are they saved to a internal projeqtor directory?

Can they be saved in a network directory (shared and mapped directory)?

Thanks
