Unsaved-change protection

See how Polyframe warns you before closing a project with unsaved changes.

← IDML files & projects Updated: 2026-08-12

Polyframe detects changes made since the last project save. It warns you before an action replaces the current document or closes the app.

This includes:

  • starting a new project;
  • importing another IDML;
  • opening another .PFP;
  • closing Polyframe.

In the Save changes? dialog, you can:

  • choose Save to keep the project and continue;
  • choose Don’t Save to continue without saving;
  • cancel and return to the project.

If saving fails or you close the file picker, Polyframe stays in the current project.

This protection does not replace regular saves. After a larger batch of work, press Cmd/Ctrl+S.

To reverse only one operation, use project undo and redo.
