Where Are Millennia Saves Located?
Millennia saves on PC under Documents My Games C Prompt tree.
Last updated
Millennia files ages of history under Documents My Games in a C Prompt tree, Paradox-publisher style. Autosaves and manuals share one saves folder per campaign era.
Late-era turns slow to a crawl. Prune old autosaves so the folder stops dragging load times.
Where Millennia stores this, by platform
Windows
%USERPROFILE%\Documents\My Games\Millennia
Save files plus settings inside; inner naming can vary with patches, so copy the whole tree. Steam Cloud syncs parts; pause it before manual restores. Multiplayer saves need the same mods on all sides.
Frequently asked questions
