I'm cleaning up my drive and noticed that after uninstalling a game, I sometimes get slightly less free space back than the game originally used. For example, I had about 160 GB free before installing it and around 159 GB after removing it. I'm guessing save files, caches, configuration folders, or installers might be left behind, but I'm not sure what else could account for the difference. Where should I look for leftover data, and what are some safe ways to find and remove it?

Make sure you’re using the platform’s uninstall option rather than deleting only a shortcut or launcher entry. Afterward, check the game’s install folder and common save locations. A disk-usage tool can help identify large leftover folders, but review each path manually before deleting it.
Some games install shared components such as Microsoft Visual C++ redistributables, DirectX files, or other runtimes. The uninstaller usually leaves those installed because other games and programs may need them, so that space isn’t necessarily leftover junk.
The difference can also come from rounding and how storage is measured. Download sizes, installed sizes, temporary extraction files, shader caches, updates, and recycle-bin contents may not match exactly. Empty the recycle bin and clear temporary files, but avoid deleting shared runtimes or unknown system folders.
Games commonly leave behind save files, settings, logs, and cache data in places such as Documents, AppData, or the game platform’s user-data folders. Check those locations after uninstalling, but be careful not to delete saves you may want later.

That makes sense. I’ll check Documents and the AppData folders before removing anything.
