Using my Hard disk

I am a bit lost about what you mean by fixed folders. There should be not quotas on the folders by default, can you please elaborate and present some examples so we can assist?

If you have additional partitions that you would like to mount onto existing folders you should read the fstab manual and adjust the fstab file accordingly; you issue with mounting is most likely because you are not trying to mount them as root. as for the directory size the only reason I can think of is that you are running out of disk space, can you please respond wish the output of "sudo fdisk -l", "sudo df -h" and something showing us that the directory size restriction that you are telling us about.

Linux based Distros are not windows in another shell, they are a different type of operating system. You can install some of your games using a windows application emulator such as wine, cedega or crossover games, but the not all games are supported and the experience differs per games since those emulators are essentially someone trying to reverse engineer the windows functions.

You will want to check each emulator's appDb to see if your games are supported and what quality level they are, the websites are below.
