How to remove the system compressed file displayed in the Win10 system disk cleaning tool

  
Prior to the Win7 system, disk cleanup was an important way to increase the speed of your computer. Although the system after Win7 does not need to manually perform disk cleaning, disk cleaning is still an important tool in Windows system. It can save disk space by deleting unused files in the system.
By default, this tool runs a simple mode that only allows the user to delete files associated with the current account. However, users can delete more useless files by switching to advanced mode, such as Windows update patches and service packs. In the Win10 preview, advanced mode added more features than before. What is currently discovered is the “System Compression” option (this option probably does not exist if your computer has been cleaned before).
However, if you want to see this option, you need to run the Disk Cleanup Tool in Administrator mode; or switch from Normal mode to Advanced mode by clicking the "Clean System Files" button.





































Select “Run as administrator"
2, select your system disk in the pop-up window (usually the default is C drive), and then click OK. After that, you need to wait for about a dozen seconds (depending on your computer, wait patiently, will come out), the disk cleanup window will pop up.
3, find the "Disk Compression" option, you can check to delete it.
It is still not clear what data is being compressed, but from the description file, this mechanism uses embedded NTFS compression to compress files to free up disk space. Old Windows users may remember that there is a "Compress old files" option in WinXP's Disk Cleanup Tool, but this option has been removed from the Vista system. Compressing data can free up a lot of disk space. This feature is useful if your Win10 Preview system has limited disk space. However, this feature is not mentioned in the official documents.
Disk cleanup After several Windows systems, the overall functionality hasn't changed much, despite some changes. So when it comes to slow computer running cards, using disk cleaning is also a good choice.
