Because this is a "split" archive, you cannot open it individually. You must have (e.g., .001, .002, .003, and .004) in the same folder to "put together" the content.

Filenames starting with "SS-Vio" are frequently associated with:

: Select "Extract Here" or "Extract to [Folder Name]" .

: Right-click the first file (ending in .001 or sometimes just .7z ).
