How to Resize Disk Partition in Windows 7

Similar to Windows Vista, Windows 7 also has the option to resize partitions, this means you can shrink or extend partitions. The Disk Management in built utility is able to do the job of shrinking and expanding partitions and it does not require any 3rd party utilities. To manage your partitions, open Control Panel and type “partitions” or “hard disk” in the search bar on the right corner and you can see the link “Create and Format Hard Disk Partitions” under administrative tools.

This will open up the disk management utility for Windows 7.

Disk Management

To shrink any volume, right click on the desired volume and select the option “Shrink Volume”. This will open up the Shrink Volume window and you need to specify the amount of space you want to shrink.

Shrink Volume

If you want to extend any volume in Windows 7, right click on the drive to be extended and select “Extend Volume”. In the next step you need to specify the amount of space by which you want to extend the volume.

extend volume

Please note that extend volume for any drive will work only if there is continuous free space available on your hard disk.

  9. ansal k.m, One hard disk which is based on MBR can create four primary partitions or three primary partitions and one extended partition. If you cannot use windows built-in tool to create new partition, you can use a free partition manager tool to have a try, it is free for windows home users. Please refer: http://www.partition-tool.com/resource/partition-windows-7.htm

  10. This was a great help !!!

    For Win 7 you don’t need a partition software for lost or missing partions on an external Drive ..

    Thanks a lot !!

  11. Thanks for the info…

  12. Windows 7 built in disk management tool has shrink and extend functions, but there is some unallocated space behind this partition which you want to extend. If there is no unallocated space behind this partition, a free 3rd party partition tool is the best choice. I search in google and find many partition tools, such as diskpart, easeus partition master……

  26. I have a laptop with Windows 7 64 bit. Sadly, my engineering program and Auto 2007 will not run on this, and they want BIG bucks ($3,700) to get newer versions.
    I would like to partion the drive (500 GB) to load XP Pro on the other side so I can keep with my older, but still very useable software.
    I just partitioned the drive after I shrank it, but I think I made a mistake because I don’t know how to get XP Pro in there, so will probably expand it and start over.
    Any suggestions on which software to use to partion and get XP Pro on there?

    Thanks
    Rob

  27. looks like my first didn’t make it.
    What software would you recommend to partion Windows 7 64 bit so I can load XP Pro on it to run my engineering programs- they won’t run under windows 7.

  60. Hi,

    Could someone please tell us when we will shrink volume in win7 so is there are any chances to losses Data or window cruppt.

  61. Thank you very much for very helpful tips on how to partition the hard disk on Windows 7.  Although it does not give me the desired volume of space as I wanted in my hard disk.  At least, I could partition my hard disk into two partition as back up for all my files which is separate partition of drive C or system files.  Thank you very much as this help me in easy partition without purchasing an expensive software for partitioning my hard drive.

  62. When I click on Shrink I get an error message “The service cannot be started, either because it is disabled or because it has no enabled devices associated with it”.  Any advice to overcome this error?

  63. i’ve lot of free space in my c drive.But it allows me only some part of that space to shrink

  64. I want to extend the drive c(from 58 to 100gb) but while right clicking i did not find the option of extending volume of c drive

  65. i did not find the option of extending the volume of c drive (shrinking the volume is right there

  66. That was too easy! Thank you!!

    Running Windows 7 64-bit Home Premium on a 128GB SSD drive (and liking it very much, thank you =)) Finally decided to upgrade C: to a 256GB SSD (Seriously, I think going to 512GB would be a sign of illness.). I created a fresh repair disk and image of C: (imaged to a USB drive), swapped the hardware and used the repair disk to restore to the new home of C:. Windows dutifully restored as though to another 128GB SSD and left the rest of the drive as unallocated.

    Do I really need a BS degree in MS and to have studied all of the documentation associated with Windows 7 to know how and where to find the answer to “Where’s the beef?!”?

    Nah! The answer was right here!

    Woohoo!

  67. This is quite useful but i couldn’t click on the expand button after i shrank a file.

  68. I tired to do what you said, but the drive I need more space on (C) would not let me expand it after shrinking D. Why would itn’t it let me?

  69. My OS(C) is full and when shrinking C, it doesn’t let me to extend the size. How come? What should I do?
