Why do you need shrink volume?
Many people face the problem of imbalanced allocation of volumes which may cause
troubles like computer crash, disk failure and so on. Especially the lack of system
space will make a computer work very slowly even leading to data loss. In such
situation, if there’s enough free space on one volume, you’re capable to create a
new volume through shrinking.
How to shrink volume with Disk Management
Because "Extend Volume" and "Shrink Volume" these two features
are added to Disk Management since the appearance of Windows 7, you can shrink
volumes through this built-in tool. Following steps will tell you how to do it in
Step 1: Open disk management.
Step 2: Right click the volume you want to shrink (here is D) →Shrink Volume.
Step 3: Decide the amount of space to shrink.
Step 4: After confirmation, a new unallocated space will appear
after D drive.
It’s easy to create a new partition with this unallocated space. While you will
notice if you want to extend C or E drive now, the option "Extend Volume"
is greyed out. Anyway, Disk Management has a great limitation in resizing
partitions. 1st, there must be an unallocated space on the same
disk when extending a volume. 2nd, the unallocated space must be
adjacent to that volume and on its right side. 3rd, you can not
shrink a volume beyond the point where any unmovable files are located.4th, "Shrink Volume" only makes the unallocated space
locate behind the volume you shrink. Thus, it seems that you need hire a third-party
software for help.
