As a free, safe and easy-to-use partition software and disk manager, AOMEI Partition Assistant Standard enables you to optimize disk space usage, change disk partition type and perform other tasks based on disk partitions. Some key features include resizing, moving, merging, splitting partitions without data loss, migrating OS to SSD, convert MBR to GPT disk, creating Windows PE bootable media, etc.
To get started, launch AOMEI Partition Assistant, and then all hard disk partitions information will be shown out in the main fresh interface.
Scenarios 1: Resize partition in Windows 7
In this example, we will shrink D: partition and extend C: drive. Right click on D: partition and select "Resize Partition", in the pop-up window, drag the left slider bar rightwards.
After clicking "OK", you will find D: partition was shrunk and an unallocated space is also released behind C: drive.
Right click on C: drive and select "Resize Partition".
In the pop-up window, drag the right slider bar rightwards to add the unallocated space.
To save changes, click "Apply" on the toolbar.
Scenarios 2: Create partition in Windows 7
AOMEI Partition Assistant provides two ways to create a new partition in Windows 7. One is to create a partition with unallocated space, and the other is to create a partition from an existing partition. In this example, we introduce the first way. Right click on an unallocated space and choose "Create Partition" in the drop-down menu.
In the pop-up window, you can label partition, change drive letter and adjust partition size by dragging slider bar.
- Partition Label: Choose your own special name to partition so that you can get better understanding on this partition.
- Drive Letter: Select the provided drive letters in the drop-down menu. (You also can choose "None", which means this newly created partition will be hidden)
- Create As:
- Two choices - Primary partition and Logical partition.
- Primary partition is used for setting active; Windows operating systems or other systems start from primary partition.
- Logical partition, to some extent, it is extended partition.
- File System:
- NTFS, FAT32 and FAT.
- NTFS supersedes the FAT file system as the preferred file system for Microsoft’s Windows operating systems nowadays.
- FAT32 and FAT are old file systems; they are simple and readable to work on a large number of operating systems. They can not support the file which is larger than 4GB.
After all the settings are completed, click "OK" and then click "Apply" to save changes.

Format partition: you could set partition label and file system as you like, about the cluster size, we suggest you do not change it, click "OK":
Click "Apply" on the toolbar to commit the changes.
Method 2: Partition hard drive with Windows 7 Disk Management tool
Disk Management is a tool built in Windows 7 which can be used to manage partitions and perform disk-related tasks. To open Windows 7 Disk Management, press "Windows+R" hotkey and type "diskmgmt.msc" in the Run window. And then click "OK" or hit "Enter".
If there is no unallocated space, you can shrink a volume. Select the disk you want to partition and right click on the partiton (here is C: drive). In the drop-down menu, select "Shrink Volume".

AOMEI Partition Assistant Vs Windows 7 Disk Management
Compared with AOMEI Partition Assistant, there are lots of restrictions in Windows 7 Disk Management.
Extend Volume: you cannot extend a volume even though there is unallocated space on the disk. Disk Management only allows you to extend a volume to contiguous unallocated space behind it. If not, the "Extend Volume" will be greyed out. However, AOMEI Partition Assistant enables you to add non-contiguous unallocated space to a partition.
Create Partition: if disk style is MBR, you may receive two errors as below when creating partitions with Disk Management. Howerver, in such case AOMEI Partition Assistant also can create partitions.
- If the MBR hard disk drive already contains four Primary partitions, you may receive "The operation you selected will convert the selected basic disk(s) to dynamic disk(s)".
- If the MBR hard disk drive already contains three Primary partitions and one Extended partition, you may receive "You cannot create a new volume in this unallocated space because the disk already contains maximum number of partitions".
Apart from the restrictions metioned above, AOMEI Partition Assistant also brings some features that Windows 7 Disk Management doesn't have. To view all the features, please click here.
