File issues

  • The file is running slowly after it's opened.

    Your file contains large pictures. Export an optimized version of the file (see Adding images).

  • The Notebook file is corrupt and can’t be opened.

    The file may be corrupted if you are trying to open a Notebook file and one of the following messages appear:

    • "Can't open the file. "

    • "This file is corrupt and cannot be opened."

    To fix this, create a new Notebook file. Drag the corrupted file into a blank page in the new file. If the corrupted file's contents appear, save the file as a new file and it should open normally.

    Tip 

    Create regular backups of important files to prevent data loss in the unlikely event a file is corrupted.
