How to extend c drive in windows 7

Most often, it is necessary to change the disk volume when, when installing Windows, the required size of the system disk was incorrectly calculated (also when buying a PC – it is often not very convenient to partition the disk: either there is only one partition with Windows, or the size of the system partition is very small).

In general, a similar operation to resize partitions can be done even without installing additional programs, if you have Windows 7, 8, 10 installed (if XP – use the link to special software for formatting, partitioning hard drives, link below).

Now I will show with a specific example where and how to press.

Programs for working with hard drives  (HDD) and solid state drives (SSD): splitting, formatting, defragmentation …  

 Increase the size of the “C: ” drive

(Actual for Windows 7, 8, 10. Without losing data and additional programs)

STEP 1: open disk management

Important : in order to increase the size of the “C: ” drive, you must have free space on some other disk partition (part of which we will take).

Modern Windows operating systems have a built-in utility for formatting and partitioning disks. It is called – disk managementOf course, the first step is to open it.

To do this, press the Win + R key combination.

Win + R

Next, the “Run” window should appear – enter the command  diskmgmt.msc in the “Open” line and press Enter (or OK, see the screenshot below).

Then the required utility should start …

STEP 2: separating some of the free space

Now we need to select the disk partition on which there is free space, and “take away” it for subsequent attachment to the “C: ” disk partition.

For example, I have several sections:

1. “C:” – 132 GB (see screen below );

2. “D:” – 751 GB (which has 187 GB free, and I will give part of this space  to the “C:” section).

To do this, right-click on the “D:” section and select the “Shrink volume”  option (note that the data should not be damaged!).

Then Windows will think for a minute or two: it will analyze the free disk space to assess the possibility of compression.

Now you need to specify how much free space you want to take away on the disk. In my example below, I took a figure of 5000 MB (i.e. 5 GB).

After the partition is compressed – you should see how you appear unallocated space on the disk (the rectangle with black stripe on top, see the screenshot below)This is the place and can now be attached to another disk partition.

STEP 3: attach unallocated space to the “C: ” drive

Right-click on the disk to which we want to attach unallocated disk space (in the current example, we attach it to the “C: ” drive), and select the “Extend volume” option from the menu.


If your Extend volume option is not active and is grayed out (you cannot press it) – read a couple of suggested solutions at the bottom of the article

Next, you will be prompted to attach an unallocated area on the disk (those 5GB that we took away from another disk partition in the previous step). Select them and click next.

In general, the last step is to agree with the operation by clicking on the “Finish” button.

All! Now your system drive is 5,000 MB larger.
