Extend C drive to make programs open faster

If your system disk is almost full and the computer is running slowly, you can speed up Windows 10 by extending the C drive. We know that most of the software is installed on the C drive. If the C drive has little space, it will obviously affect the running speed of the computer and software. Therefore, the programs will take forever to open on Windows 10.

How to extend C drive without deleting for formatting? Use EaseUS Partition Master, which enables you to allocate free space from other drives to C drive directly without any data loss.

Except for resizing or move partition, EaseUS Partition Master provides more one-stop disk partition features to solve low disk space issue, clone disk, merge partitions, and create/delete/format partition.

Now, download this powerful disk management tool to extend C drive with ease.


Step 1: Launch EaseUS Partition Master

Run EaseUS Partition Master

Step 2: Increase C drive space

1. Shrink partition to free up unallocated space:

Right-click on a partition next to the C: drive and select "Resize/Move".
Drag either end of the partition to shrink and leave unallocated space behind the system C: drive and click "OK".

2. Right-click on C: drive and select "Resize/Move".

Extend System partition

3. Drag the system partition end into unallocated space so to add space to C: drive.

Add space to C drive

Step 3: Keep all changes to extend C: drive

Upgrade HDD to SSD without reinstalling

SSDs become more popular and are thinner, lighter, and faster compared with HDD. To make Windows running more quickly and smoothly, migrating OS to SSD is a very useful way.  But how to transfer OS from HDD to SSD or even from bigger HDD to SSD without reinstalling? EaseUS Partition Master provides the simplest solutions.

Note: The operation of migrating OS to SSD or HDD will delete and remove existing partitions and data on your target disk when there is not enough unallocated space on the target disk. If you saved important data there, back up them to an external hard drive in advance.

Step 1. Run EaseUS Partition Master, select "Migrate OS" from the top menu.

select migrate os

Step 2. Select the SSD or HDD as the destination disk and click "Next".

Warning: the data and partitions on the target disk will be deleted. Make sure that you've backed up important data in advance. If not, do it now.

Then click "Migrate" to continue.

Step 3. Preview the layout of your target disk. You can also click the disk layout options to customize the layout of your target disk as you want. Then click "Proceed" to start migrating your OS to a new disk
