Where Does PrusaSlicer Store Config?
PrusaSlicer's config folder per OS, vendor bundles, and the override for synced setups.
Last updated
PrusaSlicer keeps presets and INI state in one config folder per OS with printer, filament and print trees below it. Vendor bundles like PrusaResearch.ini sit in a vendor subfolder and refresh from updates.
The in-app shortcut is Help then Show Configuration Folder. Power users sync the folder across machines with symlinks or launch with --datadir pointing at a shared copy.

Frequently asked questions
How do I back up all PrusaSlicer profiles?
Copy the entire config folder for your current version. On upgrade PrusaSlicer copies forward from the previous version folder, so keep the newest one as master.
Where are third party vendor bundles?
Under vendor in the config folder as .ini plus .idx files. Drop new bundles there with matching thumbnail folders, then restart to pick them up.
