2] Remove the small data files (for Call of Duty Modern Warfare only)

In case you are encountering this issue specifically with the Call of Duty Modern Warfare game, you can fix the issue without uninstalling the game. Since the Call of Duty Modern Warfare game is quite a huge game and uninstalling it would take a lot of time and bandwidth. So, if you want to save time and bandwidth, uninstalling the game completely is not recommended.

Instead of uninstalling the game, you can delete small game data files to avoid the Scan & Repair loop. This will enforce Battle.net to verify the integrity of game files again and then attempt to restore the missing game files.

To delete the small game data files for Call of Duty Modern Warfare, try the below steps:

1. Firstly, launch the Battle.net client and then tap on the listing associated with the Call of Duty Modern Warfare game.
2. Now, press the gear icon present for the game, and from the appeared context menu, click on the Show in Explorer option. Doing so will open up the game’s installation folder on your PC.
3. Next, exit the Battle.net game launcher and close all the tasks associated with it using Task Manager.
4. After that, inside the installation folder that you opened in step (2), delete all the folders except the Data folder.
5. Then, open the Data folder, and in the search bar, type “.idx” to view only IDX files.
6. Now, delete all the files with the .idx file extension.
7. Next, open the sub-folder insider the Data folder and delete all the files that have a size of less than 2MB.
8. After that, launch the Battle.net client and select the Call of Duty Modern Warfare game entry, and press on the Update option. It will now attempt to re-download the missing download files which will basically enable you to avoid the Scan & Repair loop.

In case this solution didn’t work for you or you are experiencing this problem with some other game, no worries. We have got one more fix that will help you resolve the issue. So, move on to the next fix.
