Purging a file removes all previous versions of an Inventor file.
Autodesk Inventor saves one or more versions of each file, depending on the application option for number of versions to keep. The versions of a file are saved in the Old Versions subfolder of the folder containing the file.
You can purge individual files, all the files in a folder, or all the component files in an assembly. The Purge All operation purges files in the top-level folder as well as files in subfolders within that folder.
Before purging, close the files in Autodesk Inventor.
A message box displays the status of the purge operation.
