Local History
A Local History of a file is maintained when you create or modify and save a file. Each time you edit and save a new version of a file, a copy of it is saved in local history.
Each state in the local history is identified by the date and time the file was saved.
This allows you to compare your current file state to a previous state, replace the file with a previous state, or restore a file that was deleted.
Note:
There is no Local History associated with Projects or with Folders.
