Once you’ve made a change in one of your files in the briefcase, a new version of the file will be saved. Do you regret the change, only return to the previous version again.
The briefcase supports versioning of files. Each time you download a file, make a change to it and save it again, the file version number increase. It is always the latest version that is displayed at the top of the list in the briefcase. In this way one can easily see when the last change was made and by whom. You can go open each different version and if you do not want to keep a version, simply remove it.
