In order to save hard disk space on your computer, Windows 10 has a hidden native feature named Compact OS. As opposed to the built-In NTFS compression option that can only be applied to specific files & folders, Compact OS targets the entire operating system, by compressing files to free up space. Wouldn't It be great to have this at your fingertips? Well, In this tutorial, I will show you how to add Compact OS to the right-click context menu.
In simple terms, once you use Compact OS, It will compress and free up your hard disk space, thereby the operating system will run from compressed files. This Is usually done by entering a command In the Command Prompt, but to simplify the process, I'll demonstrate how to add Compact OS to the right-click of the mouse.
To achieve this, I will use a neat little Registry file, that will automatically add the Compact OS feature to the right-click menu. All that's required on your part, Is to execute the Registry file, follow a couple of prompts and the job's done. I have provided the download links to the file, at the end of this article. So without further delay, let's get this started.
Step One:Once you've downloaded the file, extract It's contents to a folder of your choice, and then double-click the Add Compact OS.reg file. It will prompt whether to add the entries to the Windows Registry, so hit Yes.
Step Two:A message will be returned, confirming that the entries have been successfully added to the Registry. Click OK to finalize the process.
Step Three:I've navigated to my computer's desktop, right-clicked on a blank area and as you can see, the Compact OS feature Is readily available. Let's test It, by clicking on Compress OS.
Step Four:As expected, It's compressing all files on my Windows 10 operating system. It may take a little while, so be patient whilst It performs It's task.
Step Five:On completion, you can see the number of files that were compressed, and also the compression ratio.
Last Step:In the event you change your mind and want to remove the Compact OS feature, simply double-click the Remove Compact OS.reg file, and hit Yes.
Final Thoughts:Compact OS, frees around 1.5 GB for 32-bit systems, and 2.6 GB for those running the 64-bit architecture of Windows. Although this Is not a significant amount of storage space, It's better to have It available than In use, particularly those who're running low on disk space.
