How does file with versions migrate when exporting from SharePoint to filesystem?
All the different versions of a file will be migrated to the File System and for each version of the file, there will be one file created, with its original title and will be numbered accordingly, in the File System.
Example: If the name of the original file in SharePoint is Migrate and the file has five versions, then after migrating to a File System, all the versions of the file will be named as Migrate (1), Migrate (2), Migrate (3), Migrate (4) and Migrate (5).
