What is unallocated space used for?
Unallocated space, sometimes called free space, is the logical space on a
hard drive that operating system can write to.
In order to take full use of storage space, you can create a new partition or extend partition with unallocated space. For example, you may need to merge unallocated space to
system partition in Windows 10 when a low disk space warning appears.
Make unallocated space
Not every disk has unallocated space according to the installation, but there are two
ways to create unallocated space in Disk Management:
Delete volume. This
method is not recommended because it will wipe data on the partition. In this
case, you should do backup in advance, which takes more time.
Shrink volume. There
won’t be data loss with this approach while some limitations exist. “Shrink
Volume” only makes the unallocated space locate behind the volume you
shrink. In other words, you can’t extend or merge unallocated
space to system partition in Windows 10 directly if you
shrink other volumes.
By this token, you’re suggested to employ a third-party partition software that helps
you merge and manage partitions easily.
Merge unallocated space to system partition via AOMEI
AOMEI Partition Assistant is
an easy-to-use disk/partition software with which you’re able to merge unallocated
space to C drive in Windows 10/8/7 by a few of clicks without losing data. No matter
how much unallocated space exist, you can add all to system partition once as long
as they are on the same disk.
Step 1: Install and launch AOMEI Partition Assistant. If
there’s no unallocated space, make some via “Resize Partition”.
Step 2: Right click C drive. Select “Merge Partitions”.
Step 3: Tick all unallocated space then click “OK”.
Step 4: It will go back to the main interface and pending operations
are listed. You may redo before clicking “Apply” for final execution.
Of course, it not only enables you to merge unallocated space to system partition in
Windows 10, but also lets you merge
two drives in Windows 10. Anyway, many advanced features are available in
AOMEI Partition Assistant which will help you manage your computer better.
