I hope I post my question in the right places. In fact, last Saturday, when trying to install a game on my Windows 7 laptop, a popped-out message said that my C partition was in low disk space and this game could not be installed. Today, in this morning, when installing a file program, the same message was given and stopped my installation again. But, I had checked that all the rest partitions, like D, E and F, all of them had enough free space left. So, I think perhaps I can move some free space of these rest partitions to my D partition. Is it possible for me to go on? What can I do to resolve this low disk space problem? Please, help me!
