Re: Have you backed up YOUR files lately?
.d2s
Character files - everything about your character is stored in here. Stats, skills, items, exp, etc.
Technically all you need to backup. (I think your maps are stored in here too, but not 100% sure. If not, I'd guess they would be in the .map file)
.ma0 - .ma3, .map
Records how much of the map you've explored. Diablo will generate these if missing.
I keep these because I play full clear, and I like to see where I've explored. Optional to backup/transfer.
.key
File that holds your hotkeys. Diablo uses default or last used (don't know which) when it can't find it, and makes a new one.
Optional to backup/transfer, but you should if you have custom hotkeys.
.d2x
Gomule/ATMA stashes. Items stashed are in these, so you should backup the stashes you want to.
gomule projects
Found in X;\path\to\Gomule\projects or /path/to/Gomule/projects
in the projects folder, each subfolder is an individual project eg. the default one is \Gomule\projects\Gomule
in each project folder:
Clipboard.d2x - holds any items left in the the Gomule clipboard
project.properties - lists paths to char/stash files and is where your muled out gold is stored
Gomule.backup - backup folder for clipboard.d2x, safe to ignore
to backup all projects, just copy the "projects" folder, or choose which subfolders you want to copy
ATMA stuff
Found in X;\Program Files\ATMA V\
.cfg files - holds paths to previously opened chars/stashes. Optional, safe to ignore
ATMA_config.ini - holds your ATMA settings and muled out gold
