Thanks Jim for that pdf I don't think I've ever seen that, it looks pretty comprehensive, will have to look through that.

Some of the UserTracks will be compressed with winrar .rar, you can use that or 7zip.
Just go to your RealTracks folder bb\RealTrack then right click on UserTracks folder Send to Desktop create shortcut.
Now when you open the rar files just drag the yellow folder out onto the "UserTracks" shortcut.
