Show Compressed and Encrypted Files in Color in Windows 10

File Explorer, the default file manager app in Windows 10, is able to show compressed and encrypted files in color. This can be very useful because it allows the user to quickly identify those files. Here are two methods you can use to enable this feature.

Encrypting File System (EFS)

For many versions, Windows has included an advanced security feature called Encrypting File System (EFS). It allows the user to store files and folders encrypted, so they will be protected from unwanted access. Other user accounts cannot access your encrypted files, neither can anyone from the network or by booting into another OS and accessing that folder. This is the strongest protection which is available in Windows to protect individual files and folders without encrypting the whole drive.

When a file or a folder is encrypted, File Explorer shows its icon with a lock overlay icon at the top right corner. Additionally, its file name can be shown in green color.

NTFS compression

NTFS compression makes certain files and folders smaller. Unlike ZIP file compression, with this compression type, you do not need to create an archive file. Compression will happen on-the-fly and the files can be accessed transparently as they were before compressing. Certain files like images, videos, music which are already compressed won't be shrunk but for other file types, it can save you disk space. But keep in mind that it affects performance. This is because of extra operations the OS has to perform when the file is accessed, copied out of a compressed folder or put inside a new compressed folder. During these operations, Windows has to decompress the file in memory. As it follows from the name of the feature, NTFS compression doesn't work when you copy your compressed files over the network, so the OS has to decompress them first and transfer them uncompressed.

When a file or folder is compressed, Windows 10 displays a special double blue arrows overlay over their icon.

Note: Windows 10 supports NTFS compression natively like previous versions of the OS, but it supports a number of newer algorithms including LZX, which was not available prior to Windows 10.
