Gothic 3 Deleting old save games

I want to delete a bucn of old saved games because It is becoming a long list and takes longer to load but if I have to do this one by one it will take an eternity.
is it possible to delete some straight from the installmap? or could this corrupt the others or give problems otherwhise?

an other question wich probably belongs to the spoiler section :

Yes, just go to My Documents, make a Gothic 3 Backup Save folder, and cut/paste the savegames you want to remove into the backup folder (always nice to have in case you need it). If you decide you don't want it at all, just delete it.

i normally use WinRAR to create an archive of the whole savegame folder then delete the individual save games starting from the oldest. btw, they come in pairs - *.g3sav & *.g3savdat.
