Although Steam, one of the largest gaming distribution platforms in the world, updates itself all the time, some Steam errors still bother its players. One of the errors is that Steam says not enough disk space even though there is a lot of space available.
Regarding the different software and hardware configurations you use, there are 5 different solutions to fix the error: Steam not Enough Disk Space.

Solution 1: Reboot Computer

Situation 1: Steam’s client updates itself very frequently, and some updates configure the core of the Steam client.

Situation 2: There are some conflicts when the third-party software and Steam are both running.

Facing the above situations, the easiest way is to reboot the computer and then play games to check if the issue is fixed or not.

Note: Save all your works before rebooting computers in case of data loss.

Solution 2: Change the Path of Installation

Step 1: Open the Steam client and then click on Steam which is present at the top left side of the screen. Once inside the Settings tab, navigate to the Downloads tab.

Step 2: Click Steam Library Folders at the top of the window.

Step 4: Now you will be asked to select a drive. It is highly recommended to select a different one from where you were initially installing the program. After selecting the drive, create a new folder and name it, and click OK and select the new directory.

Step 5: Go to the Steam store to download and install a game, the client will first ask you which directory you want to install the application. Select the one you just created. After the downloading, check if the problem got solved.
