Steam is one of the most popular digital distribution platforms in the world. From 2003 when it was first released until today, millions of users worldwide enjoy downloading and playing games through it.

In step 2, make sure you have a default folder. I had a perfectly good open and working folder, but it wasn’t set as default so steam thought I had no space.

Grace is right. Even if it says ‘yes’ on the default folder, just right click on it and set it as default folder again. I run multiple partitions of Windows 10 and somehow that messes with Steam’s default folder.
