I am using pogoplug as a shared drive for our project directory. Is there a setting that will allow for a read-only prompt on files when edit mode is being used from another end?

Also, I just recently lost a PDF portfolio. Is it a better practice to make all document changes locally and then save (or sync) to the drive? I did not even have a temp file on the popoplug when I searched to recover?

Forgive the language; I am not technical.

Thanks,

Dave
