My Local Disk (C 525MB free of 111GB.New Volume (D 405GB free of 427GB.Seagate Expansion drive (G 1.93TB free of 2.72TB.I keep getting a message saying I have low memory with a red line on Local Disk (C.I have mainly downloaded games installed.Do I have to delete programs with Control Panel-uninstall programs to free space? Does the pc use only the Local disk to store games or can I use the Seagate expansion drive without uninstalling games?
