If your computer runs slower than usual, it may be time to defrag your hard drive. When you save files on your PC, the data is usually broken up and stored in multiple locations on your hard drive. This can cause fragmentation. If your hard drive is fragmented, it can take longer to access files, resulting in a slow PC performance.  Here’s your step-by-step guide on how to defrag Windows 10.

This guide will show you how to defrag Windows 10 using two methods: manually and automatically with the Disk Defrag feature in BoostSpeed.

Let’s begin.

What Does Defragmenting Do?

Defragmenting optimizes the data storage on your computer’s hard drive. Here’s what it means. When you save or remove files from your PC, the data gets fragmented and stored on your hard drive in different places.

The longer your computer takes to retrieve the various pieces of data scattered on your hard drive, the slower your PC becomes. That’s because when you defragment your hard disk, the information is reorganized so that each file is saved in a single, unbroken block.

This can improve computer performance because data can be accessed more quickly and efficiently. You can defragment your PC manually or automatically, and it’s a simple process that can improve your computer’s speed.

How to Defrag Windows 10 Hard Drive

There are several ways to defrag your computer. We’ll show you how to defrag a hard drive in two ways: manually and automatically with Auslogics BoostSpeed. Let’s start with how to defrag a computer manually:

How to Defrag a Hard Drive Manually

  • Click on the search bar, type “Defragment and Optimize Drives,” and open.
  • Choose the hard drive you want to defrag
  • Click “Optimize.” This begins the defragmentation process after determining how fragmented the disk currently is. This process may take a few hours to complete. Until then, don’t do anything too taxing on the computer.

How to Defrag Windows 10 with BoostSpeed

How to Defrag Windows 10 Hard Drive with Auslogics BoostSpeed

Auslogics BoostSpeed is one of the industry-best PC optimization software with numerous features to improve computer performance. One of its main features is the Disk Defrag tool, which allows you to defragment your hard drive’s data to enhance PC performance.

Using Auslogics BoostSpeed Disk Defrag has several advantages. First, it contains a robust defragmentation engine that can defrag your hard disk quickly and effectively, boosting your computer’s speed and performance.

It can also assist in preventing future fragmentation by merging unused space on your hard drive. Furthermore, the user-friendly interface of Auslogics BoostSpeed Disk Defrag makes it easy to use, even if you’re not tech-savvy.

The Auslogics Disk Defrag has a scheduler that lets you decide how often your hard disk should be defragmented, among other defragmentation options.

What Kinds of Drives Can You Defragment with Auslogics Disk Defrag?

Using an HDD or SSD, you can defragment your computer with Auslogics Disk Defrag. But, usually, conventional defragmentation doesn’t work on SSD and may even shorten its lifespan. Here’s why.

Solid-state drives have become increasingly popular as an alternative to traditional hard disk drives. SSDs are more efficient than traditional hard drives, but they have issues.

Rather than relying on moving elements to store and retrieve information, SSDs use electronic memory cells. This means that no part of the device is touching any other part. So, defragmenting an SSD won’t help your computer run faster.

This is because no “small arm” can move around the memory cells in the device to retrieve information from different parts of the device.

However, you can still use Auslogics Disk Defrag to improve an SSD’s performance. Its primary function is to lessen the amount of write requests sent to the storage medium.

The main problem with SSDs is that their flash memory cells can only withstand a certain number of write cycles. So download Auslogics BoostSpeed and use the Disk Defrag feature to effectively defrag your SSD or HDD.

Next to the Defrag button, you’ll see a checkbox labeled “After completing” that allows you to specify an action to be taken after completing the disk defragmentation. For example, you can shut down the PC, put it in sleep mode, hibernate, or close the program.

The disk defragmentation program also has a colorful, interactive cluster map as one of its features. You can see the files that make up a given square by clicking on it. You can even defragment selected files by right-clicking them and going to “Defrag Selected.”

SSD Optimization with Auslogics Disk Defrag

Disk Defrag optimizes system and file operations and reduces the number of write requests, both of which can increase the lifespan of a solid-state drive. Optimizing your SSD involves two steps:

  • First, select SSD Optimization in the left menu pane of the Disk Defrag tab.
