Saving notes and highlights to a separate file
Notes and highlights you add to a PDF document are not saved in the PDF data, but are added to the file as extended attributes. Those can sometimes be lost when archiving the PDF file or sending it over email.
You can save the notes to a separate .skim file, for backup or to send them by email.
To save the notes to a separate file:
- Choose File > Export….
- Select "Skim Notes" from the File Format popup, choose a location to save the notes to, and press OK.
It is important that the notes file is associated to the PDF file. Therefore it is best to choose the same file name for the .pdf file and the .skim file. In that case, Skim will automatically offer to add the notes from the notes file when you open the PDF file.
