Cloud Storage
At a glance
- Connect Google Drive or OneDrive and open / save projects through the same themed file picker
- Sign-in happens in your system browser — JetCad3 never sees your password
- Connections restore automatically when you sign in on another machine
- Fully optional: the app runs offline-first, local files always work
Settings → Cloud Storage connects a Google Drive or OneDrive account to JetCad3. Clicking Connect opens your normal system browser to sign in — the app never handles your password, only the access token Google or Microsoft grants it. Once connected, both drives appear in the sidebar of the file picker alongside your local folders. Cloud storage is part of the paid tiers; on Free and Hobby the tab shows an upgrade link instead and the picker's cloud rows stay disabled.
Working with cloud files
Browsing Drive or OneDrive in the picker behaves like browsing local disk: rename, new folder, cut/copy/paste, trash, and drag-and-drop all work the same. Opening a cloud project stages a local working copy, so editing stays fast even on a slow connection — autosave and crash recovery run against that local copy too. When you hit Save, JetCad3 writes the file locally first and only reports success after the upload to the cloud actually completes, so a dropped connection can't silently eat your work. Themes, G-code files, and the text editor can open cloud files directly as well; a few flows, like machine profile import/export, remain local-only for now.
Moving between machines
Connections are tied to your JetCad3 account. Install the app on a second computer, sign in, and previously connected drives restore automatically — no re-authorizing each provider by hand. If a token has been revoked in the meantime (you changed your password, or disconnected from the Google/Microsoft side), JetCad3 shows a short reconnect message instead of a cryptic error. Signing out clears the cloud tokens from that machine, so a shared shop computer doesn't leave your drives open to the next person. A Test connection button on each provider card confirms everything is talking before you rely on it.
