Q: Why do some file and folder names show up in blue instead of black in Windows?
A: If file names or folder names show up in blue, it is because file compression or encryption is enabled on that file or folder. Windows automatically compresses files that do not get used frequently, and displays those files in blue. You can change this behavior with the following steps:
