Excellent your answer quality! Happen when you put a new ped, you change several sub-folders of Mod: Maybe, mppatches and patchday3ng and patchday6ng and x64v.
Unfortunately, a ped isn't in a single folder. It would be much easier.
If I understand you in the right way, the idea would be to make a backup of each subfolder that was changed and not a 100% backup of Mod "Master" Folder.
Very, very thanks JonaQ
