FAQs
How It Works
Tech Specification

What is the purpose of disk partitioning software and do I really need it?

Disk partition software is used to manage hard drive space by dividing it into multiple sections (partitions), which allows for better organization of files, dual-booting operating systems, and potential performance improvements. It's particularly useful for tasks like resizing, merging, or formatting partitions, especially when you run into problems or limitations with built-in Windows tools. For anyone who wants to manage data and system better, or to optimize overall computer speed and performance, you’ll need a disk partitioning software and it’s perfect to start with a free one.

What is the cheapest way to create a separate partition in Windows?

Creating partitions allows you to organize data better. For example, you can store your operating system (OS) on one partition (like C:) and your personal files or documents on another partition (like D:). This helps prevent data loss if your OS gets corrupted.
The easiest and cheapest method for dividing a partition is to use AOMEI Partition Assistant Free edition. Not only just cost-effective, but it is also versatile, easy to install and operate for all none computer professionals. To create, merge and adjust partitions as needed can be done in a few clicks.

What's the best way to expand or shrink a disk partition?

To simplify your operation, avoid functionality limitations and data loss, it’s suggested to use a reliable and safe partitioning software for the task. With specialized partition tools, you can enjoy more user-friendly interface and navigation, resize non-adjacent partitions, move data and partitions without affecting files, resize partitions between MBR and GPT styles, and much more flexibility and advanced features.

How to free up space in partition?

Besides cleaning up your computer manually (which takes quite some time and efforts) or if your manual cleanup didn’t work out well, you’re advised to use a comprehensive disk management tool. It helps tweak your partitions to the most ideal allocations in the first place, and is able to automatically detects and removes large & unused files, identified files, temporary files and registry errors wholly in a few clicks. Compared to do it manually on one’s own, there may be data loss risk and it’s highly computer skill demanding.

How to extend a C drive partition?

Effective methods to increase C drive partition space include freeing up space on C drive via moving apps to another drive, running disk cleanup, and physically extending C drive. To physically extend C drive, if you have adjacent unallocated space on the C drive partition, Windows built-in Disk Management can be competent for the task. Otherwise, i.e, for non-adjacent unallocated space, you have to use a specialized partitioning tool. For other cases, if your disk itself doesn’t possess enough space, it’s advised to upgrade the disk to a larger one.

I basically gave up on trying to switch my HDD to GPT without formatting it. I downloaded AOMEI Partition Assistant and it switched it in seconds without deleting all my stuff! I love you! Thanks!

Isaac Reynolds

I don't do this very often, but I wanted to say thanks for an excellent product! This was the only way I successfully merged my C & D drives. The Expand option for C was greyed out, but your product worked effortlessly and was very user-friendly. Thanks again.
