Why Need to Increase C drive in Windows 11
"How can I get more space on my C drive without losing data? Recently, a 'low disk space' pop-out balloon has been showing in the Systray, warning me to extend the size of the C drive. I can't see either format the C drive or delete other partitions since I have data saved on all of them. So, how can I make more space on my C drive without formatting or removing partitions?"
The speed with which an operating system runs on a Windows computer is primarily determined by the amount of free space on the C drive. However, as the number of installed software and its related data storage on the C drive increases, your system partition will run out of space, and your computer's performance will decrease.
Usually, more than 90% of users desire to extend C drive space because the free space is approaching the 200MB, 80MB, and 50MB thresholds. You may have tried to free up space on the C drive by deleting unnecessary files, uninstalling applications, or cleaning out the recycle bin. However, these are ultimately temporary fixes. It won't take long before your C drive is completely full. So, how can you increase C drive space and totally solve the C drive low data storage problem? If you eagerly want to know, then read this guide carefully!!

EaseUS Partition Master is an all-in-one partitioning utility that works with Windows 11 and all lower versions. With this tool, you can easily extend the C drive with or without unallocated space.
When there is free space on your system disc, just resize the C drive to make additional room. When your hard disc has no unallocated space, you can use the EaseUS partition manager to increase the C drive with free space on other partitions.
With the EaseUS disk management tool, you may do the following hard drive management without losing any data or exerting any effort.
Features of EaseUS Partition Master:
- To safeguard privacy, resize/move partitions, create, format, delete, and merge partitions, and wipe disc data.
- Copy and clone an entire drive to another, and migrate the operating system to SSD to speed up Windows without reinstalling.
- Convert a logical partition to a primary partition or a primary partition to a logical partition, FAT to NTFS partition, MBR disk to GPT, or GPT disk to MBR.
Method 1. Increase C Drive by Allocating Space from D Drive to C Drive
Moving free space from one partition to another would be simple if the two partitions were on the same disc. For example, if you wish to move the free space from the D drive to the C drive or move the free space from any partition to another disc, you can do so using these simple methods.
The EaseUS partition magic tool is all you need. It has an Allocate Space feature that allows you to move unused space from one partition to another on the same disc.
Following the installation of the EaseUS disc management program, proceed with the instructions to allocate free space to another drive. As an example, let's look at D and C drives.
Step 1. Right-click on the D: partition with enough free space and select "Allocate Space".
Step 2. Select the target partition - C: drive and drag the partition panel rightward to add the free space from D: drive to C: drive. Then click "OK" to confirm.
Step 3. Click the "Execute Operation" button and click "Apply" to start the process of moving free space from D: drive to C: drive.
If you have unallocated disk space, you can shift it to the desired hard drive by resizing hard drive partitions with EaseUS Partition Master.
Method 2. Increase C drive by Merging Partitions in Windows 11
When there is no space on your disk, and you do not want to remove or format the hard drive, you can use EaseUS partition management software to enlarge the C drive and its "Resize/Move partition" option.

Disk Management is included with Windows 11 and lower versions and is regarded as a handy tool for assisting users in resolving partition and disc issues. You can perform the following steps to extend the partition.
Step 1: First open Disk Management. To do so: Open the WinX menu by pressing Win + X, and then click to open the Disk Management.
Step 2: In Disk Management, the system (main) partition is navy-blue, whereas the unallocated partition is black. Select "Delete Volume" from the context menu when you right-click on the adjacent partition. Then, to confirm this action, click "Yes."
Step 3: Right-click on the system partition (C:) and select the "Extend Volume" option to examine if an unallocated space has been generated to the right of partition C.
Step 4: The Extend Volume Wizard will appear; click "Next" to complete the process.
Quick things to keep in mind:
- If the Extend Volume option in Windows Disk Management is greyed off, use the Delete partition or Delete partition override command instead.
- If there is no unallocated space, the user must erase the C disk's adjacent partitions to extend the C disc.
- Before erasing a partition, always make a backup of your files.
