How to Backup Steam

PC Only Content Information on this page is PC specific.

This Guide will allow you to make backup copies of your character files, often referred to .dun files.

Head over to your Steam directory:

Steam > steamapps > common > dungeon defenders > Binaries > Win32

Inside this directory you'll find the DunDefHeroes.dun and a DunDefHeroes.dun.bak (you may also see DunDefHeroes.bak). these files are your local character save files (often referred to unranked characters).

Copy these files to any other location to make a back up.

Note: TE said use this method for now, until they can make a proper backup program.

Kalafiorek mentioned on the forums that you can make a batch file to do this for you.

Open Notepad, paste this information into it, save as DunDef Backup.bat.
