How do I share a file without others deleting it? Basically I shared a file with a client, she deleted it off her Dropbox which deleted it off of mine. How do I prevent them from having any power over the file save for safe download and still share?
Dropbox is a file syncing service, not a file sharing with ACL service. So there's no way to prevent them from deleting, especially if you're using the Dropbox client. It is however very easy to revert accidental file alterations (which includes deletion). This can most easily be done on the Dropbox online control-panel for your account.
