1. Delete the active download folder or rename it

1.1 Delete the folder

1. Head to File Explorer and navigate to the following location:

C:\Program Files\Steam\Steamapps\Downloading

2. Every game on Steam is assigned a unique number. Inside the downloading folder, open the first folder with a number. Check to see if it’s a part of the problematic game.

3. Remove the folder from your computer.

4. If Steam is still operating, close it. Restart Steam and try again to install the game.

Consider temporarily disabling the firewall and antivirus before moving on to more detailed troubleshooting. If that doesn’t work, move on to the next step in the troubleshooting process.

The corrupt game files could also be the cause of the corrupt disk issue. You can try deleting the game’s files in progress and restarting the download using the Steam client.

1.2 Rename the folder

1. Navigate to the following directory in Steamapps to find the Downloading folder:

C:\Program Files (x86)\Steam\Steamapps

2. To rename the Downloading folder, right-click on it. Change the name of the folder to Downloading12.

3. Then, under the Steamapps folder, make a new folder called Downloading.

4. Start Steam and try to install the game that caused the problem. The game should now be available for download and installation.

As stated in the steps above, rename the download folder to anything else and create a new folder called downloading.

2. Reinstall the Steam client

1. In Windows search, type control panel and then select Control Panel from the list of results.

2. Select Programs and Features from the drop-down menu.

3. Locate Steam in the list of programs, right-click it, and choose Uninstall.

4. Restart your computer and download Steam again from the official website.

5. When you launch Steam, you should see that all of your game data is still there.

6. If this isn’t the case, copy the Steamapps folder from the backup disk to this location:

C:\Program Files (x86)\Steam folder

You can try reinstalling the Steam client as a last option. The game data and installed games are not deleted when you uninstall your Steam client; just the client is removed.

The game data and files from the folder will be picked up by the Steam client when you reinstall it.

However, just to be safe, make a backup of the Steamapps folder by going to the following location:

C:\Program Files (x86)\Steam

After you’ve made a backup of the Steamapps folder, you can remove the Steam client.

3. Verify the integrity of the game files

1. Go to Steam.

2. Choose Library and then choose Games.

3. Select Properties from the right-click menu of the malfunctioning game.

4. Select the Local Files tab from the Properties menu.

5. Select Verify integrity of game files from the drop-down menu.

6. Steam will do a check on the game file to see whether it’s corrupted. Proceed to the next step if the verification was successful.

If the game files are corrupted or missing, the corrupt disk error can occur. The Steam client has a built-in program that checks and confirms the integrity of game files.

4. Repair the Steam Library folder

1. Go to Steam.

2.  Choose Steam and then choose Settings.

3. Click the Downloads tab in Settings menu.

4. Click on Steam Library Folders from Content Libraries.

5. Right-click on the Steam Library Folder (or custom library folder) and choose Repair Library Folder.

6. If an issue is found, Steam will scan the folder and attempt to repair it.

7. Try downloading the games again to check if the problem has been addressed.

If the issue is caused by the default Steam Library folder, use the Repair Steam Library Folder option to resolve it. Here’s how to go about it.

5. Change the download folder / Steam Library folder

1. Go to the Steam menu, then choose Steam and Settings.

2. Select the Downloads option from the drop-down menu.
