Fix: Ark Failed to Open Descriptor File

What is the problem?

The problem is that the game cannot find the required data files in order to run. This is typically caused by either the game not being installed properly, or by corrupt or missing files.

Section: How can I fix it?

There are a few different ways to fix this problem:

1) Re-install the game. This will ensure that all of the required files are in the correct place and are not corrupt.

2) If you have a backup of the required files, you can copy them into the correct location. This can be done by finding the game’s installation folder ( typically something like C:\Program Files\Ark Survival Evolved\ ) and copying the files into the appropriate sub-folder ( for example, the “ShooterGame\Content\Paks” folder ).

3) Use a file recovery program to scan your hard drive for missing or corrupt files. This can be done by downloading and running a program like Recuva ( https://www.piriform.com/recuva ). Once the program has finished scanning, it will show you a list of recoverable files. Choose the ones you need and recover them to the correct location.

4) If all else fails, you can try to reinstall the game from scratch. This will delete all of your game data, so be sure to back up anything you want to keep first.

How to fix the problem?

If you are receiving the error “Ark Failed to Open Descriptor File”, it means that the game is having trouble accessing a required file. This can be caused by a number of things, but the most common causes are corrupt or missing files, and incorrect game settings.

To fix this problem, you will need to first check for corrupt or missing files. You can do this by verifying the game files through Steam. To do this, right-click on the game in your Steam library, and select “Properties”. From here, go to the “Local Files” tab and click “Verify Integrity of Game Cache”. Steam will now check your game files and replace any that are missing or corrupt.

Once you have verified your game files, you will need to check your game settings. In the “Launch Options” for the game, you will need to make sure that the “-nomemrestrict” option is set. This setting tells the game to not limit the amount of memory it can use, and can often fix problems with missing or corrupt files.

If you are still having problems after doing these things, you may need to contact Steam support or the developers of the game for further assistance.
