Do you want to change partition size? On this post, I will show you some ways to resize partitions on Windows 10.
With the progressive increase in capacity that has suffered the classic internal hard drives and the low price they have experienced, it is widespread to find that the new computer mounts storage equal to or greater than 1 TB and of course have two or more partitions, one for system and another for data.
These partitions that often come already in the new computer that you buy, may have dimensions that you consider appropriate and therefore you will not touch them for the rest of the life of the disk.
Now, it may also be that the measurements of the partitions are not which you want, and you have to extend or reduce them so that they are to your liking.
Therefore, today you will see how you can reduce or extend your partitions through the Windows 10 Disk Manager, without using any external app and with quite good results, although with some limitations that you will also see.
First of all, we need to verify that the drive is NTFS
- Open the File Explorer
- Right-click on your Drive and select Properties
- There look for File System: NTFS
Once confirmed that you File System is NTFS, use one of these methods to resize your partitions.
Method #1: Resize Partition using Disk Management
Disk Management is a dynamic disk and volume manager that you can use to resize your partitions
- Press the keys Winkey + R to open Run
- Type the command: diskmgmt.msc
- Press Enter to open Disk Management
- There you can see all your partitions
- Right-click on your partition to resize and select Shrink Volume
- Enter the amount to space to resize and click Shrink
- Now, you can see your partition resize to your desired amount, and now there is an Unallocated space.
- Now if you want to add unallocated space to your partition, right-click on the partition and select Extend Volume
- Click on Next and select the Unallocated Space and click on Add
- Now, click on Next and then in Finish to apply the resize.
This is the way that you can resize your partitions using graphical tools. But if you only have access to the command prompt or want to try something different check the method below.
Method #2: Resize Partition using Command Prompt
To resize partitions in Windows 10 using the Command Prompt, you need to use the tool diskpart
- Press the keys Winkey + R to open Run
- Type the command cmd and press Enter to open the Command Prompt
- In the Command Prompt type the command diskpart and press Enter
- in DISKPART type the command list volume and press Enter
This command shows you all your active partitions
- For this tutorial, we want to reduce the size of volume 2 by 2048 MB
- For that, type the command select volume 2
This command selects the volume to work using the syntax select volume #
- Now, you have two commands:
shrink to reduce the size
extend to increase the size
- Those commands need the desired or minimum size like this:
shrink desired=2000 to resize the partition to 2000 MB
shrink minimum=2000 to resize the partition by 2000 MB
- Now, I will use the command shrink minimum=2000
- Use the command list volume to check your partition
There check how volume 2 now have 90 GB
Method #3: Resize Partitions with EASEUS
Today there are very reliable and simple to use apps that will allow you to work with partitions that are currently in use and modify them without losing data. The tool we will use is EaseUS Partition Master as that you can download from the following link.
Before starting, I recommend you to always work with backup copies since the slightest failure during the process can make you lose all the data of the partitions on which you are working.
I also recommend defragmenting the partitions so that the data is as contiguous as possible and reducing the probability of error.
Once you download and install EASEUS Partition Master, run the app.
To resize or change the size of a partition, the first thing you need to do is select the partition on which you want to work and, from the options that appear on the right, select Resize.
A new window will appear from which you can choose the free space that you want to leave both in front of and behind the active partition. The final area of your partition cant be inferior (or close) to the space you have already occupied on the disk.
You can use both the graph that appears and create new sizes manually in the text boxes.
Once you have configured the new values, confirm the window and the task will be automatically placed in the list of pending tasks. To apply it, click on the Execute operation button, and the program will start working.
This process usually takes a long time, so you must wait patiently and, also, avoid using the computer during the process.
Once finished, if everything has gone successfully, you will have a partition with a new size and an unpartitioned space next to it. This space can be used, for example, to create a new partition or, to expand another partition.
