Nice idea but has bugs

Attempting to save documents from email results in two copies made, one of which cannot be deleted from your iPhone device ever, and which remains visible and readable to anyone accessing your Wifi shared drive. Do not ever use this to share a file that you dont want to be made permanently public... Large attachments could also fill up your remaining space.
