Diablo III saves account data in Documents\Diablo III. Heroes sync to Battle.net, local files hold settings.
Last updated
Diablo III is always online, so heroes live server side. Local files hold settings and account preferences in Documents under Diablo III.
Reinstalls cost keybinds, never characters. Copy the folder for comfort. Seasonal progress and paragon never touch your disk in a way worth protecting. Hardcore deaths are final server side, no local file restores them.
Where Diablo III stores this, by platform
%USERPROFILE%\Documents\Diablo III
D3Prefs.txt plus account data. Heroes sync server side. Copy for settings migration.
