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.
