I know this isnt the right place to ask but I dont know what to do?

i have had roblox studio for some time in my C disk or whatever its called, and that disk has recently ran out of space. So whenever I open roblox studio it gives me the error "there is not enough room on your disk to install roblox" and even happens when i delete and reinstall the application. I have another disk that has wayy more storage and whenever i redownload roblox studio, I place the studio folder inside of that huge disk full of open storage and it still says that there isn't enough disk space? I honestly dont know what to do, I've tried to watch tutorials but none of them are what im looking for. If anyone knows the solution it would be amazing if they could help me.

1. This is the right place
2. Roblox installs on your main storage unit, so you can't just put it in another storage, you're gonna need to empty your main storage a bit.
