I have 3 main folders inside Infogrames folder:
1. GP4 - for CSM, MODs I usually play GP2 MOD and DTM
2. GP4 Update - where I keep all updates and a huge folder named WIP with subfolders named by Track Project: hundreds of pictures by year, videos, .dwg files, textures, etc, etc, etc...
3. GP5 - Formula 1 basically. And this is the way I play it:
3.1. Championship, race by race and results computed on a separated excel sheet;
3.2. Replace Mark Webber with my own name, surely
3.3. 100% races, all F1 tracks, even if I have them at a single dat file stage.
3.4. Randomic weather, ACE, Performance based on Paulo´s Performance Excel Sheet
Own helmet, own sponsorships for RB8, Own cockpit for private use, Samuele´s HUD.
Play on keyboard, steering wheel only for online sessions for F1 2011 with PrBlanco.
And most important: Backup every two weeks on a portable HD
