Thanks oldmariner I'll have another look
They don't make it easy. I played the game on XP in 2009. I tend to keep my saves. The save folder is not labeled SAVE. The folder is in my documents titled after your user name, such as ME or Fred, Sue or whatever. The saves themselves are named by date. Such as
2009-05-16_14-31_4F1JO.sav an actual title from one of my saves. 14-31 must be the time of day as the saves are ordered by date and time or so it seems.
The last five characters 4F1JO have no similarity to other saves in the list. No sequential order and the letter number configuration is random regarding their use of numbers and letters. Some have numbers where letters appear in other saves.
If you do not find them under my documents/user name you can try doing a search using the extension of the file name [.sav ] without the brackets. .sav should locate all folders with that extension on your computer. Not likely you have tons of .sav files.
Good luck
