In this age of terabyte hard drives, you might think that a guide on how to save disk space on Windows 10  is not necessary. That isn’t so. For one, older Windows computers do not have a hard drive with a huge storage space.

Besides, Solid State Drives (SSD) are still behind in terms of GB. Even if you have plenty of space, you might still want to get rid of the dead weight. This article will teach you how to declutter your drive and compress its contents to save disk space. Here’s how to compress a hard drive to free up more space!

What Is Windows 10 Disk Space?

Windows 10 needs a certain amount of space on your disk to store files, folders and apps. Windows 10 hard drive space is also used to hold system settings, user profiles and software updates.

If your Windows 10 disk space becomes too low, it may throw a spanner in the works of your system. With a full hard drive, you may face errors, slowdowns, freezes, crashes, and even the dreaded Blue Screen of Death. Which is why you need to compress this drive to save disk space.

What Is Disk Compression?

Disk compression is a convenient feature that can help you manage Windows 10 hard drive space more efficiently. It optimizes PC storage by compressing files and folders on your hard drive or solid-state drive (SSD).

Disk compression rearranges data within files, removes redundant information, and organizes storage in a more efficient manner. Your files become smaller in size, yet their functionality or usability does not suffer. As a result, you get more disk space on a PC  to store extra files or install additional applications.

How to Perform NTFS Disk Compression in Windows 10

If you want to get more storage on a PC, you can use a built-in compression tool that helps reclaim Windows 10 hard drive space. It is called NTFS drive compression, and it lets you save up to 2% of the Windows 10 disk space on your system drive.

The built-in NTFS disk compression tool is designed to apply a special algorithm to your drive and compress its contents to save disk space. This can be useful for data-based partitions that contain a lot of multimedia files but is not advisable for executables because every file you access has to be decompressed first. If you wish to proceed, perform a data backup.

And now it’s time to learn how to free up disk space on Windows 10 via NTFS disk compression:

  1. On your keyboard, press Windows Key + E. This should open File Explorer.
  2. Right-click the drive or partition you wish to compress.
  3. Select Properties from the menu.
  4. Click the box beside Compress this drive to save disk space”.
  5. Click Apply and OK.
  6. The disk compression process will start, and once it is completed, you will see a notification.

You have to know that NTFS disk compression can slow down file loading when you try to access the processed folders. Needless to say, your system’s processing power can be affected and execution will slow down. This is only a viable solution when you desperately need some extra space.
