You may want to shrink C drive to GB for system files and make a new partition for personal data or new released system with the generated space. Some users want to shrink C drive and extend D drive with the redundant space.
This may result from unreasonable partition layout when they first partition the hard drive, which may make hard drive management harder. Anyway, no matter what factor leads you to shrink the system drive, the most important thing is to find out how to do this. Following parts will discuss three methods about shrinking C drive in Windows. Here in this tutorial, it will take shrink C drive partition Windows 7 for example. However, before you start, clean up some of the crap first.
For instance, empty the recycle bin and delete useless files on the C drive. Next, create a system image for your computer. It will query volume for available shrink space. Secondly , type in the amount of space that you want to shrink by or click the up and down arrows behind the box no more than MB.
Diskpart is one of the built-in partition tools in Windows, which is an embedded product that needs to be used under Command Prompt. When shrink C partition with Disk Management, you are likely to encounter one confusing situation. For example, you have GB on your C drive.
However, when you plan to shrink this partition only to find the available space is only MB according to the querying results. While at the top of the screen, it indicates that C drive has GB of free space. What is wrong? For more information, see Additional considerations. When you shrink a partition, any ordinary files are automatically relocated on the disk to create the new unallocated space. There is no need to reformat the disk to shrink the partition.
If the partition is a raw partition that is, one without a file system that contains data such as a database file , shrinking the partition might destroy the data. You must be a member of the Backup Operators or Administrators group, at minimum, to complete these steps. Note the number of the simple volume you want to shrink. Selects the simple volume volumenumber you want to shrink.
Shrinks the selected volume to desiredsize in megabytes MB if possible, or to minimumsize if desiredsize is too large. When you shrink a partition, certain files for example, the paging file or the shadow copy storage area cannot be automatically relocated, and you cannot decrease the allocated space beyond the point where the unmovable files are located.
If the shrink operation fails, check the Application Log for Event , which will identify the unmovable file. When you provide the querycluster parameter, the command output will identify the unmovable file that is preventing the shrink operation from succeeding.
In some cases, you can relocate the file temporarily. For example, if you need to shrink the partition further, you can use Control Panel to move the paging file or stored shadow copies to another disk, delete the stored shadow copies, shrink the volume, and then move the paging file back to the disk. If the number of bad clusters detected by dynamic bad-cluster remapping is too high, you cannot shrink the partition.
If this occurs, you should consider moving the data and replacing the disk. Follow Is there a problem that happens if I make shrink to my only one partition hard drive from windows and from outside of windows I mean another program?

Basm Allah Alrahman Alrahim What I Know that every part of any file at windows when it saved or installed that the operating system will try to find the first good place sectors at the hard drive to fill it with data and that mean if we have empty sectors at the beginning of the hard the new installation file will be saved there until it fill that sectors and complete installation on another part of the hard sectors so it can be at the end of the hard , at Linux the installation files are installed at Sequential sectors not like windows so most of the time we don't need defragmentation except the case of near of full hard , So when I make shrink to any partition there is a danger when there is fragmentation , of course all operating system designer talk that in consideration but some time a problem may happens when make shrink , I tried that my self and I got a disaster , I loss the partition , so what we must to do?
