Why need a partition tool for Windows 7?

Nowadays, Windows 7 operating system is still a popular choice for computer users in spite of the rapid growth rate of Windows 11/10 installation. No matter which operating system you are using now, the hard disk is an indispensable component of a computer. You need to install and run OS from it, and it offers the necessary space for you to store all kinds of data.

To make the fullest use of the disk space, you had better create several partitions for different purposes. The typical strategy is to create a C partition for OS, D partition for applications/programs, and other partitions for personal data. Thus, you need a partition manager for Windows 7 to better manage your disk partition and optimize disk space usage without data loss.

Windows 7 native partition tool-Disk Management

To manage disk partition in Windows 7 64 bit and 32 bit, you can first try Windows 7 built-in partition tool-Disk Management. It can help you do some basic disk management such as creating volume, deleting volume, formating volume, changing drive letter, setting active partition and more.

Part 1. To open Windows 7 Disk Management, there are 3 ways you can try:

1. Right-click "Computer"> "Manage", select "Storage">"Disk Management" in the submenu.

2. Press “Windows and R” together on the keyboard, type “diskmgmt.msc” and press “Enter”.

Open Disk Management Cmd

3. Click "Start" >"Control Panel" > "System and Security" > "Administrative Tools", then choose “Create and Format Hard Disk Partitions”.

In the Window 7 Disk Management, you'll see all connected hard disks with detailed partition information (type, file system, status, capacity, free space..).

Part 2. What Windows 7 built-in partition manager can do for you?

To see what you can do to your disk partition via Windows 7 Disk Management, right-click any partition. Compared with Windows XP, Windows 7 Disk Management has added the “Shrink Volume” and “Extend Volume” options, which allows users to resize the partition.

Dm Shrinl Extend Volume

Shrinking volume is easy to finish: right-click the partition, select “Shrink Volume” from the drop-down menu, and follow the onscreen instruction to complete this operation. But for the “extending volume” task, the Disk Management might let you down because this function only works with a precondition-the partition you are going to extend must be followed by an allocated space on its right side. Otherwise, the “Extend Volume” will become grayed out and unclickable (as shown below).

Extend Volume Grey Out

This restriction bothers most Windows 7 users when they want to extend C drive to fix the common low disk space issue on the system drive. To extend C drive without unallocated space on its right side, deleting the neighboring volume (usually D drive) is a guaranteed solution. But that will remove everything inside as well. In this situation, a more powerful partition tool Windows 7 is necessary.
