Why shrink volume in Windows 7?
Most users face the problem of imbalanced allocation of volumes or said partitions. It may cause many troubles like computer crash, disk failure and so on. Especially the lack of system space can make a computer work very slowly even lead to data loss. In such situations, one ideal way is to shrink one volume to increase another. Sometimes, maybe you just want to create a volume. It can also be realized by shrinking.
Limitations of Windows 7 Disk Management
“My E Drive has 120GB free space, why I can just shrink 70GB?”, “I have an unallocated space on the disk but I can’t extend volume C with it.” such kind of problems are commonly seen. Although compared with Windows XP/2003, the built-in Disk Management in Windows 7 has new functions -- “Extend Volume” and “Shrink Volume”. There’s still a great limitation.
Like the example mentioned above, why only 70GB can be shrunk while there’s 120GB free space. Because you can not shrink a volume beyond the point where any unmovable files are located with Disk Management. That means no matter how much space exists before an unmovable file, it won’t be the available shrink space. In other words, maybe you are even not able to shrink a volume at all because of the unmovable files! Another example, if you want to extend volume D, but the unallocated space is behind volume C or E, your operation will not be realized, either. Disk Management just allows you to extend a volume when the unallocated space is adjacent to it and must on its right side. Anyway, how to deal with these inconveniences? AOMEI Partition Assistant is worth a try.
Shrink volume in Windows 7 with AOMEI Partition Assistant
AOMEI Partition Assistant has many functions which are designed for better disk management. It breaks many limitations that are said before. You will find instructions of how to shrink volume in Windows 7 with this freeware here. Windows 8/8.1/10 are also supported. Above all, you need download and install it. Before the following operation, three things should be noticed. 1st, check the partitions to make sure that there’s no error. 2nd, close all running applications on the volumes you want to change. 3rd, do not forcibly terminate the tasks or cut off the power in case of data loss. Then, launch AOMEI Partition Assistant.
Step 1: Right click the volume you need shrink and select “Resize Partition”.
Step 2: Move the mouse pointer to the border (either left or right side) and drag it. Then click "OK".
Step 3: Here comes a new unallocated space. And you can view the “Pending Operations” before clicking “Apply” to execute.
Please pay attention that the operation will be performed under PreOS Mode when shrinking system and boot partition or shrinking a partition where applications are running.
After shrinking, the unallocated space can be used to extend another volume by “Merge Partitions” even that unallocated space is not next to the volume. Or you can just use that space to create a new partition. In general, AOMEI Partition Assistant is able to shrink a volume without the “hinder” of unmovable files. It also has a lot of other functions which can manage your system better.
