On Windows 11, you have a lightweight file compression feature that can help you free up some disk space. The file compression feature of Windows 11 can shrink the size of the files and folders without relying on third-party file compression tools.

The feature only works with drives using the NTFS File system, and it has a few drawbacks. In low-end computers, the file compression feature of Windows 11 might affect the performance.

When you copy/move a compressed NTFS file to a different folder or drive, NTFS will first decompress the files, copy/move the file to the new location, and then it will again recompress the file. This extra process will use your CPU and RAM resources, affecting the system’s performance.

However, if you have a high-end PC, you won’t notice any performance issues while moving the compressed files between folders or drives. Here are some simple steps to enable file compression on the Windows 11 operating system.

First, open the File Explorer on your PC and navigate to the folder you want to compress.

Right-click on the folder and select Properties.

On the Folder Properties, switch to the General tab and click on the Advanced option.

On the Advanced Attributes, check the option Compress contents to save disk space. Once done, click on the OK button.

Select Apply changes to this folder only option on the next prompt and click on the Ok button.

That’s it! This will activate the NTFS file compression on your selected folder. You will notice two blue arrows above the folder. These arrows indicate the folder has been compressed.
