One of my favorite features of Dropbox is 'versioning,' which keeps a copy of every change that you make. Every time you press 'save' on a document that's in your Dropbox, a new version is saved.
There are two things I have been wondering about versioning:
What happens to changes that you make while offline?
What happens to changes when the file is renamed or overwritten?
I finally did some quick tests of this, and the answers are pretty straight-forward:
Offline changes will not be versioned. Any changes made to a file while the computer is offline are not versioned on Dropbox.com. The only version that will be saved is the one which is active when you reconnect
