It is not possible to change note type via GUI. However, it can be done manually, since any note is stored on disk as set of text and bitmap files.

  1. Run Windows Explorer, go to the directory where the note's files are located.
  2. Open the __page.opt file in a text editor.
  3. Change value of the Type field of the [General] section with the desired type name and save the file.
  4. Launch OutWiker (if OutWiker's window has already been opened, go to "Tools / Reload Wiki" to refresh the tree of notes).

Use the described procedure with caution for the syntax as well as structure of __page.opt and __page.text files depend on the note type.
