Look at your "save" folder located in "my documents\dungeon siege"

You have there all your .dssave and .dsparty files

The .dssave file represents your players on single game

The .dsparty file represents your player on multiplayer game

Send your ".dsparty" file to tank viewer

In order to make your work easier, I suggest to create a shortcut of your tank viewer and your skritpad into your "send to" folder

As you can see your .dsparty is composed of three files:

Info.gas - Party.gas - Portrait.bmp

Point the three above files together and press "extract"

Open "Chars" folder (on the left side of the new window)

Add a name to this new folder (on the right side of the new window) as shown bellow and press extract

The above action will automatically open a new folder (I called it Gog) into your "Chars" folder

I suggest to open a new folder for each new .dsparty char
