Last year, after installing the Windows on my computer, I had divided my computer internal drives into four partitions. But, unfortunately, recently, there was only below 1GB of free space left on my C partition. Moreover, in this morning, when trying to install a video editing tool there, a low disk space notice also popped out and stopped me to use it. So, I think, perhaps, it is necessary for me to extend this partition space right now. Am I right? Do you have any way for me to fix this low disk space problem? Do I have to change another computer drive? Thank you for any advice!
