Hi Viv,

>After the initial save I think it only stores changes to the file so a coherent copy isn't available outside of SourceSafe. The data is actually stored in an array of folders supposedly optimised for efficiency.

The other way round... VSS saves the most recent version. To serve older versions VSS stores the difference to the most recent one. If you check in a file, VSS determines the differences to the last one and replaces the copy in the database with the latest file.
