How to extend partition size in Windows

Windows itself is tailored with two ways through which an individual can easily resize the partitions. Whether it be Windows 7, Windows 10, or Vista, you’ll be encountered with robust Disk Management that allows you to shrink and expand partitions. However, it will not be wrong to mention that using third-party utilities will add extra feature-rich functionalities, but you have to go through an extra step that can also charge a few pennies. 

A Brief About Resizing Partitions in Windows 

The process of modifying the partition's size either by extending or shrinking it is known as resizing partitions on Windows. Also, an individual can divide a partition into two and add free disk space to the continuous logical space on the hard disk. 

However, hard drives can be separated into different partitions and dedicated spaces that can store various files. Users can separate Windows, installed applications, individual data, etc., with the help of partitions. 

Majorly, it is observed that the default partitions lag in meeting the demands of users. Some partitions can get small enough to store all your data and make your system run out of space. Therefore, your system might get consequences like slower speed or other issues.

Luckily, all windows users can use the system’s built-in tool to resize partitions and manage them without any data loss. To get started, an individual must open the Control Panel and search for “partition” into the search box; for Windows 8 or 8.1, users should run the Start Screen search. And you have the flexibility to use both the start menu or the control panel search if you’re using Windows 10.

How Partitioning in Windows Helps?

Partitioning in Windows will help you have from the following:

  • C drive is running out of space.
  • Your Windows computer is getting slow.
  • The frequent notifications about low space that pop up on the screen.  

Along with this, the following is the list of the most common issues that gets eliminated with the help of partitioning:

  • Utilizing Disk Space to the Fullest

By default, it is likely to happen that a partition may get overloaded with data, whereas the other one is having tons of available space. Therefore, with the help of partitions, you can manage to utilize these spaces to the fullest without impacting several storage spaces. 

  • Reduces Disk Space Issues

When the storage space runs out, Windows notifies users with the message like "You are running out of disk space on Windows (C:). To free space on this drive by deleting old or unnecessary files, click here" or "You are running out of disk space on Recovery (D:). Click here to see if you can free space on this drive." 

But after you adjust the partitions and utilize the free spaces or even extend their sizes, you are more likely to receive lesser messages regarding disk space issues.

  • Dividing One Big Partition 

Every new system comes with one big partition of the hard drive by default, leaving a lot of free space. This one big partition can be divided or shrank and can result in several new partitions in unallocated space.

Few Tips Regarding Resizing Partitions

Indeed the process of partitioning is easy hard data. But certain things are needed to be considered before resizing partition to enhance data security:

  • Backup all the data you want to resize because there are minimal chances that users may lose their valuable data due to the interruption through certain causes.
  • In the case of the larger partition capacity and big amount of data, computers generally take a lot of time. Therefore, ensure that your computer doesn’t go on hibernation or sleep mode.
  • Ensure eliminating all the errors of the partitions you want to extend or shrink because they may block the partitioning process. 
  • To make the process ends successfully, do not shut down the computer and eliminate any sudden power failure chances. 

Extending Partition Size in Windows Using the Disk Management System

  • Step:1

To get started with disk management,  search for the same in the taskbar. But if you’re using Windows 7, search for the same in the Start Menu or write on the start screen on Windows 8.1. After this, click on the “Create and format hard disk partitions” option.

  • Step: 2

Right after this, redirect to the partition that you wish to resize and right-click on it. Now to resize it, a contextual menu will open in front of you:

  1. For increasing the partition size, click on the “Extend Volume” option. 
  2. But if you wish to make the partition smaller, click the “Shrink Volume” option. 

  • Step: 3

If no unallocated space is available near the partition, the “Extend Volume” option will be grayed out. Therefore, increasing the size may get nearly impossible. Similarly, if the partition you wish to reduce is flooded with data, you will not be able to make it smaller, and the “Shrink Volume” option will grey out.

  • Step: 4 

However, to increase the partition size even after experiencing lesser space, click on the “Extend Volume”. It will open the disk Management with a screen containing “Extend Volume Wizard.” Hit next to proceed. 

  • Step: 5

Now select the total space you want to add to the partition. This can be dependent on the total free space available near the partition. By default, all the free space is selected by Wizard that one can check from the Selected list.

  • Step:6

You can specify the space you want in MB by selecting the option of “Select the amount of space in MB”. Right after this, click on the Next to continue.

  • Step:7

At this step, the “Extend Volume Wizard” will summarize the settings you implemented. Check if they are suiting your needs and proceed accordingly. 

  • Step: 8

Finally, the Wizard will close, and partitioning will be implemented. 

What to do if Extended Volume Gets Grayed Out?

  • Check whether or not the Disk Management is opened with administrator privileges and permissions.
  • Ensure to have unallocated space near the partition you want to resize. You can opt to delete the volumes present in-between the unallocated space and the partition.  
  • In Windows, partitions can only be resized into NTFS or ReFS file systems. So, it is important to format files in these systems only. 
  • Make sure to use the partitioning scheme of GPT if your disk is larger than 2 TB.

If you are still facing issues regarding extending the partition volume, navigate directly to the Microsoft community.  And if you don’t find an answer, post a question regarding your query where other professionals will help you.

Extending Partition Size with PowerShell or Command Prompt, and the DiskPart Tool

To attain the same results with the command lines’ help, run the Command Prompt or the PowerShell for resizing the partitions. Follow the steps mentioned below:

  • To start disk partitioning tools, run the diskpart command. 
  • Now to list all the partitions, run the list volume command on your Windows computer. Search the Volume column to identify the partition’s volume number that you will resize. 
  • The next step is replacing the # with the partition’s volume number.
  • To extend the partition, type extends size = custom size. After this, enter the customized value in MB (megabytes).
  • However, for making the size smaller, you have to run the shrink desired = custom size command in MB.

Conclusion

The blog covers all the necessary information one needs for resizing partitions without using any third-party tools for that. As we've mentioned, it is surprisingly easy to In early all the Windows version (majorly 10/8/7/XP) these steps can help either extend or shrink the partition as per the requirement. Both Disk Management and using command prompt will help you achieve the end goal without getting overwhelmed.

Computers has always fascinated me since I was a kid and here we are. I love travelling for 2 reasons: the first one to see a new part of the world and second (the most important one) to experience the rich culture hidden among the country and people. I'm pretty good at cooking but very poor when it comes to baking.
