Repartition hard drive for Windows 7 ASAP

Windows 7 has been released for a long time, so many Windows 7 users encountered the Low Disk Space problem – system C drive is running out of space and becomes full. It is easy to understand: many kinds of files write into C drive continuously every day, such as Windows Updates, programs of Games, Projects, Word processor, etc. Together with other files such as temporary, cache, logs, C drive will be filled up sooner or later.

This is the reason why people want to resize partition and extend C drive on Windows 7. However, many people do not pay enough attention about the low disk space that leads to some issue occur. For example, system performance down, computer stuck, reboot or even crash, so repartition the hard drive as fast as possible when there is not enough free space in system C drive.

Then how to repartition disk without losing data? There are two choices: Windows 7 Disk Management and third party partition software such as NIUBI Partition Editor Free, but to extend C drive, Disk Management is limited.

Microsoft enhanced the disk partition management ability from Windows Vista. Besides basic management to create, delete and format volume, you can resize partition with Shrink and Extend volume functionality in Windows 7 Disk Management.

Fortunately, you can accomplish with 3rd-party free partition manager such as NIUBI Partition Editor Free, which is 100% free for home users and 100% clean without sponsored ads or bundles.
