概要: File compression is an easy way to reduce the size of a file and save storage space. This post will offer practical ways to enable NTFS Compression to compress files & folders in Windows 10.

Sometimes, we need to free up some storage space on the Windows 10 drive, when the drive is running out of disk space. There are many ways that can free up the disk space on Windows 10, such as uninstalling unnecessary programs and Apps, deleting the files you don’t need, using disk cleanup programs, saving files to the cloud storage tools, etc.

In addition to the methods mentioned above, Windows 10 OS Compression and NTFS Compression are also feasible and straightforward ways to free up disk space. Let’s go through several ways to compress Windows 10 files and folders.

Tip: Though file compression is safe, you’d better back up the essential files in case data loss occurs.

Practical Ways to Compress Windows 10 Files to Free Up Disk Space

Compress Windows 10 Operating System to Make More Disk Space

Step 1: Type CMD in the Start menu search field and choose Run as administrator 並點擊 Yes to run Command Prompt.

Step 3: The system will now notify you if the feature is active. If it shows that Windows 10 is not in the Compact state feature, the system can be easily enabled.

The system will show you the current status when compressing OS binaries. When the compression is finished, the system will display the results, including the number of compressed files and the compression ratio.

Windows OS compression will gain up to 2 GB of free space on the drive. If you need to know the exact free space, you can check the properties of the drive.

The system will begin to compress the files to restore the changes and shift the operating system back to its normal state.

The system will inform you once the changes have been reverted to their original state successfully.
