Saving a backup of my characters?

[quickrabbit5]

Hi, I am going to reformat my computer soon and reinstall windows, so I want to save my character from Titan Quest. I AM using Immortal Throne.

I know there have probably been a ton of threads on this, but I have seen tons of people plagued with issues on losing quests, caravan items, ect. ect so I want to make absolutely sure that I don't lose anything.

I have vista ultimate 64 bit, and im reinstalling to vista ultimate 32 bit, if that makes a difference.

In addition I am using a D2D downloaded version of Titan Quest. (Couldn't find it in any stores, steam wouldn't work)

Basically, what steps do I need to take to save my character? I have TQ defiler if that helps in anyway to make a backup.

Thanks for the help!
