How to retrieve a corrupted file?
InDesign version: InDesign 12.1.0.56
OS: MacOS 10.13.2
Computer: iMac(Retina 5K, 27-inch, Late 2014)
I am writing an extensive family history book that presently contains 55 chapters and 11 appendices. My problem is with one appendix which became corrupted more than 2 years ago; all the other chapters and appendices are fine. Frustrated with trying to troubleshoot this 400-page appendix, I put it aside. From time to time, I tried opening the file with a new version of InDesign, but the problem remained. The symptom is that when I open the appendix, it is almost impossible to do anything with it. I can't edit it, print it, export it, etc. I get the spinning colored wheel. Recently, I have looked again to see what can be done to resurrect this file and I have tried a number of the suggestions I have found on line (such as "Troubleshooting damaged InDesign documents) to no avail. The problem is that once you get the spinning wheel, there is no way to diagnose the problem. Does anyone have an idea on how to proceed?
