Where Does Bambu Studio Store Settings and Profiles?
Bambu Studio data folder on Windows, macOS and Linux with presets, cache and logs.
Last updated
Bambu Studio stores user presets, login state, cache and logs in a per-platform data folder. Your tuned filament and process profiles live there, separate from the factory presets bundled with updates.
Cloud-synced presets also download from your Bambu account, so a fresh login restores some of it. The local folder remains the authoritative backup for everything else.
Where Bambu Studio stores this, by platform
%APPDATA%\BambuStudio
Holds user presets, config and logs. Copy it before reinstalls or major version jumps.
~/Library/Application Support/BambuStudio
Same presets and settings tree. Reach it through Finder Go > Go to Folder.
~/.config/BambuStudio
Same layout as the other desktop builds.
Frequently asked questions
How do I back up Bambu Studio profiles?
Copy the BambuStudio data folder with the app closed. Signing into your Bambu account on the new machine restores cloud presets on top.
Bambu Studio lost my presets after an update. Why?
Major versions migrate the profile store and occasionally strand customs. Restore your folder backup into the new version path and re-sync from the cloud.
