ComfyUI-SaveFile

Adds a "Save File…" option to the File menu that opens a native OS save dialog, letting you choose exactly where to save your workflow JSON.

Why?

• Save / Save As stores workflows in ComfyUI's internal storage — you can't choose where on disk the file goes.
• Export downloads to your browser's default Downloads folder.

Save File… opens a native OS file dialog, so you can pick any location on your drive — no need to move files manually after saving.

Features

• Native OS save dialog — choose exactly where to save, not just Downloads
• Saves the current workflow as a .json file
• Preserves canvas view state (zoom/offset) if enabled in settings
• Falls back to a standard browser download in Firefox

Browser Compatibility

Browser	Behavior
Chrome / Edge	✅ Native "Save As" dialog
Electron (Desktop)	✅ Native "Save As" dialog
Firefox / Safari	⚠️ Standard browser download (see below)

Firefox Users

Firefox does not support the File System Access API, so the extension falls back to a regular file download. By default, Firefox saves to your Downloads folder without asking.

To get a save dialog in Firefox:

1. Open Firefox Settings (about:preferences)
2. Scroll to Files and Applications → Downloads
3. Enable ✅ Always ask you where to save files

With this setting, Firefox will prompt you to choose a save location every time — similar to the native dialog in Chrome.
