- 📌Difficulty Level: Medium
- 👍🏻Pros: Free;
- 🧑🏻💻Best for: Experienced Windows 7 users.
- 🧰Applies to: Expand data partition in Windows 10/8/10 with adjacent unallocated space.
In this part, we'll show you how to extend Windows 7 partition with existing unallocated space - Disk Management. See the detailed steps on how to expand your partition with adjacent Disk Management:
- Please note that there must be unallocated space behind the partition which you want to expand with Windows' built-in Disk Management utility.
- Otherwise, you can't extend volume without adjacent unallocated space.
Step 1. Press the Windows key + R key to open the Run dialog. Type diskmgmt.msc and click "OK".
Windows 7 will automatically open Disk Management for you.
Step 2. Right-click on the partition you want to extend and select "Extend Volume" from the given list.
Step 3. Follow the wizard to set and add more size to your target partition, and click "Next" to continue.
Step 4. Click "Finish" to complete the extending process in Windows 7.
If there is no unallocated space, you'll need to right-click a neighbor drive and select "Delete volume " or "Shrink volume" to free up unallocated space. Back up data first if you intend to do so:
1. Open Disk Management, locate the partition next to your target one, and check its state:
2. If the partition is empty, right-click on it and select "Delete Volume" > Click "Yes" to confirm.
3. If the partition is not empty but has big enough space, right-click on it and select "Shrink Volume" > Enter the amount of space that you want to shrink and click "Shrink" to confirm.
Then repeat the steps, as shown above, to extend the partition with shrunk unallocated space in Windows 7 Disk Management.
- 📌Difficulty Level: Hard;
- 👍🏻Pros: Free;
- 🧑🏻💻Best for: Experienced & advanced Windows 7 users.
- 🧰Applies to: Increase partition size when the unallocated space is behind the target volume.
Some advanced Windows users and administrators prefer to use DiskPart command lines to extend their hard drive partition. This might be easy for them but complex for ordinary users. Also, any false operation may cause a serious result.
- Note that if the unallocated space is not behind your target volume, you'll have to use Disk Management to shrink or delete a neighbor drive in advance. Also, be careful, as using the CMD command line is easy to lose data with false operations.
Therefore, follow the operations carefully:
Step 1. Right-click Windows 7 icon and select "Search".
Step 2. Type cmd and right-click on "Command Prompt", then select "Run as Administrator".
Step 4. Type the following command lines one by one and hit Enter each time:
- list volume
- select volume x (Replace X with the target drive number. In my case, the target drive is Volume 1.)
- extend size =number (Replace the number with the size in MB that you want to add to your target drive.)
