How to Solve the Epic Games Not Enough Space Issue

The Epic Games install failed IS-DS01 error may occur to any game. In most cases, the cause is the insufficient space. However, sometimes, the cause is that the Epic Games client doesn’t detect your space and you have enough free space actually.

Whatever case you are in, the following ways may help you get rid of the Epic Games not enough space issue. You can have a try.

Way 1. Get More Space for Your Game Installation

The error says there is not enough space for the game installation. Therefore, you can check the free space in Windows File Explorer. If there is little available space, you can free up the disk space or extend the partition to get more space for the game.

#1. Free up the Disk Space

To free up the disk space, you can do a disk cleanup, delete some files, or transfer some files to another disk. Here is the guide on how to do a disk cleanup.

  1. Open Windows File Explorer and highlight This PC.
  2. In the right panel, right-click on a drive and choose Properties.
  3. Under the General tab, click Disk Cleanup.
  4. In the Disk Cleanup window, check the files to be deleted and click the OK button.

You can use the mouse to delete or transfer files easily. However, if you want to find what files are taking up most of the hard drive space, you can try MiniTool Partition Wizard.

This software can list all files including hidden files by file size in descending order. Then, you can decide what files should be transferred or deleted. In addition, this software can also extend a partition easily, migrate OS, clone hard drives, recover hard drive data, convert MBR to GPT without data loss, etc.

How to use MiniTool Partition Wizard to free up space? Here is the guide:

Way 3. Move the VaultCache

Some people report that they encounter the Epic Games install failed IS-DS01 error even after changing the game install location to another drive having enough free space. The main reason is that the VaultCache folder is still in the drive that is short of space.

not enough space in VaultCache

Vault Cache (C:\Program Files (x86)\Epic Games\Launcher\VaultCache) is used to make a copy of your games. When you download a game, the game files will be also written to this folder.

This folder is space-consuming. You can delete this folder, but it is useful when you download or install the same game again. Epic Games Launcher will check the VaultCache folder. If it finds that the same version of the game files already exists, it will use these files directly instead of downloading them again.

Therefore, I recommend you move the VaultCache folder to another drive to solve the Epic Games not enough space issue. Here is the guide:

  1. Open Epic Games and go to Settings.
  2. Scroll down to find Edit Vault Cache Location.
  3. Click Browse to change the location.
