Compress folders and files in Windows

If we are getting tight with the space on the hard drive or a partition, you can use the so-called NTFS compression . This is a standard function that Microsoft has been delivering since Windows XP and is also available with Windows 10 . With this NTFS compression, you have the option of compressing individual files or entire folders and thus saving storage space.

If your folder is compressed , all files stored in it and also all subfolders including their contents will be reduced or compressed. We will describe how this works here below.

Assume that you want to compress a certain folder, so click on it with the right mouse button and select ” Properties “.
