A folder containing our InDesign file went missing off our server. We were able to restore it from previous versions, but the InDesign file within the folder was corrupted and we are unable to open it. We receive the message Cannot Open “File Name.” The file “File Name” is damaged and cannot be recovered (Error code:5). Is there any way we can recover this file? Any time we try to do anything with the file, it crashes InDesign.
