In BM-Windream, any number of sequential versions of any file or document can be created and maintained. Only the most recent version can be modified. Previous versions are effectively secured against any accidental or intentional modifications.
The most recent version of a file is displayed directly in the Windows® Explorer. The complete version history with all previous versions is shown in the BM-Windream "Version" tab of the extended Explorer file-properties window. Any version can be opened and viewed by a simple double click.
