Recover lost changes

To prevent lost changes after an unexpected interruption, the Autosave feature must be enabled, which is the default setting.

Set up automatic saving

  1. Choose Edit > Preferences (Windows) or Acrobat > Preferences (Mac OS).
  2. Select Documents on the Categories list.
  3. If Automatically Save Document Changes To Temporary File Every xx Minutes (1-99) is not selected, select it now.
  4. In the Minutes box, specify how often you want Acrobat to save files.

Recover lost changes after an unexpected shutdown

  1. Start Acrobat or open the file you were working on last.
  2. When prompted, click Yes to open the autosave file or files. If multiple files were open, Acrobat opens all of the files for you.
  3. Save the file or files with the same names as the files you were originally working on.
