PS3 Secret Menu

[alsevillajr]

A couple of questions...need suggestions please!!!!

1) If I Rebuild Database, will it delete all saved game files? If yes...can I save game files prior to rebuild to re-install after rebuild...Please explain process

2 What is the "Restore File System" in the menu...what's the purpose???


Thanks in advance guys!!!!

Note: Is Rebuild Database same as "Format Utility" on System Settings and the only save feature that I see is to transfer data to another PS3 console....Data Sticks option?
