A NetFiles dropbox is a secure file storage area which serves as an alternative to emailing attachments. A dropbox allows identified users to write files to the dropbox folder, but prevents them from viewing (reading) the contents of the dropbox.
Important considerations: Allowing people to write to a folder may fill your space. Prevent this by setting a reasonable quota: click on the Manage icon next to the folder name, then click on the Storage Quota: link. Never allow unauthenticated users (the public) to read and write to the same folder. The potential for abuse is high and you are responsible for your own space.
