You are running out of disk space on SYSTEM (C:), To free space on this drive by deleting old or unnecessary files, click here...
In this case, we have to delete the unwanted file to get a better free space in order to ensure the normal operation of Windows. However, deleting files is not the best way, because my system disk have a total of 250GB, the system boot partition (M:) is only 20GB, and 230GB was divided to data partition (N:), it is clear that (N:) space is large enough, and now the best approach is from the (N:) divide 60GB to (M:), so that you can permanently solve the problem.
To expand the system boot partition and increase its free space, in Windows 2000, Windows XP and Windows 2003 era is very difficult to do, because their Disk Management did not provide the functions of extending or shrinking the partition, this would have to use third-party tools such as Partition Magic, Disk Director, and other partition management software to accomplish this extending.
However, in Windows Vista, Windows 2008 and Windows 7 times, it is no longer a difficult task, because Disk Management of Vista, Win2008 and Win7 has been in-built expanding volume and shrinking volume, which is very easy to use without relying on 3rd party partition utilities. At the same time, this feature can not only resize the basic partition on a basic disk, but it can also resize the dynamic system volume on a dynamic disk. Yet partition magic and other disk management tools can not handle dynamic disks. Thus, resizing a dynamic disk volume is indeed a good feature on Vista, Windows 7 and Windows 2008.
