How to Fix Steam Not Enough Disk Space Error

The "Steam Out of Disk Space" issue is really annoying players all over the world. Sometimes, customer service doesn't provide you with the exact solution. Therefore, you can now try the following solutions to remove this error.

Fix 1. Reboot PC and Steam

Shutting down your PC and Steam and restarting them will usually fix this error, as some updates and random Windows bugs can affect the core of Steam, so the restarting process works perfectly to resolve the issue. Some third-party software can also affect the download or installation of Steam games. Restarting usually prevents this non-essential software from loading, which may be what Steam needs.

Fix 2. Verify the Integrity of Steam Game Files

This is the most common method used by Steam users when an error occurs. Most games on Steam are typically tens of gigabytes in size, and sometimes, it's inevitable that some files will get corrupted. Therefore, verifying the integrity of game files can help identify corrupted game files, delete them, and re-download them to resolve the issue.

Step 1. Close all games running on your computer.

Step 2. After closing, navigate to the Steam "Game Library".

Step 3. Locate the problematic game in the game list on the left. Right-click on it and select "Properties".

Step 4. After entering the property options, find the "Local Files" tab from the navigation bar.

Step 5. Click "Verify integrity of game files" to get started.

Once done, restart the Steam game and see if the out-of-space error pops up again.

Fix 3. Clear Steam Download Cache

Steam downloads can generate too much download cache data in the cache, which can cause a lot of glitches, including this out-of-disk-space error you're facing. Clearing the Steam download cache can often resolve this issue.

Step 1. Launch Steam from the desktop and select "Steam" from the top navigation bar. Then, select "Settings" from the drop-down menu.

Step 2. Select the "Download" tab in the list on the left, click "Clear Download Cache," and follow the instructions.

Step 3. Once completed, Steam will restart itself.

Step 1. Close all Steam-related applications.

Step 2. Right-click on the desktop icon and select "Run as administrator" from the drop-down menu.

Step 3. Once Steam loads, you will enter management mode. Redownload, install or run the game to see if the problem is fixed.

Step 2. In the Properties wizard, select Tools.

Step 3. Click "Check" under the "Error Checking" section.
