→Local history

A local edit history of an →object is maintained when you create or modify this object. Each time you edit and save the object, a copy is saved so that you can replace the current state with a previous edition or even restore a deleted object. You can also compare the contents of all the local edits. Each edit in the local history is uniquely represented by the date and time the file for the object was saved. Only objects have a local history; →projects and →folders do not.
An edition is a "snapshot" of what the object looked like a point in time (as saved in the local history).
