You can lose important INDB files due to any reason, such as accidentally deleting them. Another major reason could be that you forgot to save them properly. But, there’s no need to panic, because there are multiple methods to restore these files, whether you accidentally deleted them or they were left unsaved.

What Is INDB File?

The INDB format is associated with Adobe’s publishing and page layout designing software, Adobe InDesign. Therefore, the INDB format is appropriately a shortened form of the InDesign Book.

A typical INDB file will contain a collection of individual INDD document files that form the book. This means that the INDB project file will contain all pages, indexes, page numbers, and all other formatting information.

Therefore, the main purpose of an INDB file is to compile all the documents in a single project so that they can be easily published and printed. They also make it easy to apply multiple styles across all pages, eliminating the need to edit them individually.

To create a new INDB file, simply launch Adobe InDesign and navigate to File > New book. Assign a name and save the location for the book, and it will be saved as an INDB file.

So, how do you recover lost INDB files and resume regular activities on your computer? Read through the next few sections to find out.

  • Back up your INDB files: Always back up all your important data as frequently as possible. You can automate this process by switching on automatic backup on Windows and macOS.
  • Diversify your backup channels: Having multiple backup channels greatly reduces your chance of losing essential data. Keep critical information stored in two external storage devices, and one cloud platform.
  • Use a good antivirus program: Investing in antivirus programs is always a good idea. While the onboard antivirus software on both Windows and macOS is decent, added security will further mitigate virus infection on your computer.
  • Save your work regularly: When working on an InDesign project that uses INDB files, always save your work frequently. In the event of a crash, let the program close, and avoid shutting down or force quitting Adobe InDesign, as that can also cause the INDB file to disappear.
