    Increase Partition Size in Windows 7 “I have Windows 7 and just give D drive (especially for programs as well as their updates) 40GB space at installing time. Now, I don’t dare install any software and download some large applications since there is no extra storage space on D. I just want to extend the partition in Windows 7 without formatting, because I am unwilling to backup all data, which takes me so much time. Any suggestions or wonderful solutions?”

    Disk Space Is Running out in Windows 7

    It is believed that most of you may encounter this case. When installing Windows 7/8/10/XP, Windows Server 2003/2008/2012 operating systems, you have allocated space for each partition. However, as time goes by, you store large data to your partitions and the drive is running out of space. If you want to solve the low disk space problem of partitions, you may search some solutions.

    When a certain partition is running out of space, in general, there are three methods you can use to solve this issue:

    1.Delete old or useless files: this way can take effect on partition size to some degrees and it just solves the problem temporarily. It only can release a little disk space and can’t solve your problem fundamentally.

    2.Upgrade to a larger hard drive: if you have a larger hard drive, you may consider upgrading your old disk to a larger one, but it is time-consuming to copy all disk data.

    3.Increase partition size in Windows 7: this way can help you to extend partition by releasing some free space from a big partition or getting some storage space from your unallocated space on the hard drive. It makes full use of your disk space.

    Undoubtedly, to increase the partition size in Windows without formatting your partitions is the best one among those three solutions.

    How to Extend Partition Windows 7 without Formatting

    As to the mentioned solutions to low disk space issue, extending partition size is recommended to you in Windows 7. Let’s look at the following two ways to increase partition size under Windows 7.

    Disk Management Is Restricted to Resize Partition

    Windows has a built-in partition management tool which is called Disk Management. This tool can help you to manage your partitions and disks for free. As to increasing partition size on Windows 7, you can use its “Extend Volume” feature to achieve the aim to a certain degree.

    However, sometimes when right clicking a partition, you can find “Extend Volume” is grayed out. From the following screenshot, you can see this phenomenon.

    In fact, “Extend Volume” function can’t work in three cases:

    1.If the partition you want to extend is a logical partition, but there is only unallocated space and no free space right after the target partition, this feature is useless.

    2.Or you want to extend a primary partition, but there is no unallocated space on the adjacent right side of the partition, it is still grey.

    3.If you need to extend Windows partition, the partitions must be in NTFS and RAW formats , otherwise, you can’t use Disk Management to extend your partitions.


    Consequently, Disk Management is not excellent to increase partition size in Windows 7. You need to find another professional partition manager to do this work.
