Where Are SimCity 4 Saves Located?
SimCity 4 Documents folder with Regions holding city files and plugins on PC.
Last updated
SimCity 4 stores regions and cities in Documents under a SimCity 4 folder, one Regions subfolder per region with individual city files inside. Plugins live next door, which is why a fresh install loses custom content but keeps cities.
Back up Regions plus Plugins and the whole setup survives a move. City files are small, so full-folder copies are cheap.
Where SimCity 4 stores this, by platform
%USERPROFILE%\Documents\SimCity 4\Regions
Each region is a folder of city files. Custom content sits in the sibling Plugins folder. Copy Regions and Plugins together with the game closed for a complete backup.
