Where do the Single Player Track Files Exist in (C: ) so to Delete them?

I know where the Multiplayer Tracks reside in Users\My Name\Saved Games\DCS\Tracks\Multiplayer in Windows 7.

Where are the Single Player Track files located ?

If they exist I would like to thin them out by deleting most of the tracks.

Does Single Player track files automatically save themselves like the Multiplayer tracks do?

Or do I need to initiate the Save process to actually save the specific file to my choice of where I want to stash them as a deliberate manual save ?

Thanks in advance for any help.

They exist in "Tracks" folder only if you click on "save track" after quit/exit from mission.

Thanks !
