You need to resize partition in Windows 7
A partition is a division of a hard disk drive with each partition on a drive appearing as a different drive letter. Generally speaking, you may want to resize hard drive partition in Windows 7 in following situations.
System drive is too small. When you receive the prompting message: low disk space during computer use, it is time to resize Windows 7 partition. Because you cannot even open some sort of files or applications.
Data drive is too large. Another case is plenty of disk space has been divided into one data drive. It would be a mess if you store all data on that drive. Therefore, it is necessary to change partition size in Windows 7 and then create one more partition for different sorts of data.
Unreasonable partitioning on the disk. Most PCs were partitioned before the customers take it. Some of them have only one partition named C drive, and some of them have many partitions that are not quite helpful.
Anyway, no matter why you want to resize partition in Windows 7, it is important to figure out how to perform partition resizing. In total, this passage details three easy-to-follow methods.
Resize Windows 7 partition free with built-in tools
Windows offers two different utilities with graphical user interface and command user interface. One is Disk Management and the other is Command Prompt. Let’s get to know them one by one.
Resize Windows 7 partition in Disk Management
1. Press Windows key + R key to open Run. Type diskmgmt.msc and click OK. Run as administrator. Find Disk Management under Storage tab.
2. Right click the partition you want to resize. You can select “Shrink Volume” or “Extend Volume” from the given list. Take Extend Volume for example.
To use “Extend Volume” function, there should be an unallocated space adjacent to the selected partition. Otherwise, you’ll get extend volume grayed out trouble.
If you choose “Shrink Volume”, you are likely to shrink only half of the selected partition due to hibernation files, etc. in most cases. To break the restriction, you can turn to shrink C drive beyond half.
3. Follow the wizard to complete the extending.
Resize C drive in Windows 7 via Command Prompt
1. Open Run as instructed. Type cmd and run as administrator.
2. Type following commands in sequence.
select disk n (where n is where the target partition on)
select partition m (where m is the partition you want to resize)
extend size=10240 (it will extend by 10GB)
To extend partition in Diskpart, make sure there is also unallocated space contiguous. Otherwise, the operation may not be able to complete.
Those two methods are quite simple, but their limits sometimes prevent our behavior. For instance, if there is no unallocated space on the disk, you need to delete existing partition next to the selected drive to generate unallocated space, and then perform partition extending. To extend C drive in Windows 7 without formatting, it is a wise move to choose another powerful tool.
