On a Windows Vista-based computer, the Folder versions list is blank, or you receive the following message:

There are no previous versions available.

This issue occurs when you access the properties of a file or of a folder, and then you click the Previous Versions tab.

Additionally, if you use the command vssadmin list shadows at a command prompt, the volume that hosts the file or the folder will have a list of shadow copies that are associated with the volume.
