Fix #7: Defrag Hard Drive

Defrag, which is short for “defragmentation,” is the process of rearranging the files on a hard drive so that they are easier to find. Hard drives store data in small groups called “clusters” that are spread out across the disk. Over time, as files are added, deleted, and changed, these groups can become fragmented, which means that parts of a file can be spread out in different places on the disk. This can make it take longer to get to files, which can slow down performance and cause games like Company of Heroes 3 to load more slowly and lose FPS.

Defragmenting a hard drive entails restructuring these clusters such that file fragments are stored in continuous disk blocks. This can result in faster file access times and increased overall performance, including higher FPS in games. With Windows utilities, such as the Disk Defragmenter, or third-party defragmentation software, it is possible to defragment a hard disk.

This is how you defrag your hard drive:

  1. Click Start.
  2. Select All Apps.
  3. Scroll down and look for Windows Tools, then click on it.
  4. Look for “Defragment and Optimize Drives” and right-click on it.
  5. Click Open.
  6. Click Optimize.
