Help! Roblox Player Says I Have No Disk Space Even Though My G: Drive Is Empty

You hit the nail on the head! Roblox does indeed use the C: drive for its data. If space is an issue there, it's likely causing the error you're seeing. You can try clearing some space on the C: drive by deleting unnecessary files or using disk cleanup tools. Also, consider moving some files from the C: drive to your G: drive to free up more space for Roblox.

Just to clarify, the installer you have isn't actually Roblox itself—it just installs the game. The real issue might be that Roblox typically installs data on the C: drive in the AppData folder, regardless of where the installer is located. So even if your G: drive is empty, it might still be trying to save files on your C: drive, which could be full. You might want to check your C: drive for space issues. Unfortunately, changing the install location for Roblox data isn't straightforward.
