A: 4K â also known as UHD (more on this in the next answer!) â is a picture technology that quadruples the number of pixels found in a full HD picture. These pixels are usually arranged in a 3,840 x 2,160 configuration, compared with the 1920x1080 you get in a full HD TV.
A file with the 7Z file extension is a 7-Zip Compressed file. Other types of files may also use the 7Z file extension. If you know of any additional file formats that use the .7Z extension, please let me know so I can update this information.
What is a VGZ file? Every day thousands of users submit information to us about which programs they use to open specific types of files. While we do not yet have a description of the VGZ file format and what it is normally used for, we do know which programs are known to open these files. See the list of programs recommended by our users below. We are constantly working on adding more file type descriptions to the site - the current count exceeds thousand by far, and more information about VGZ files will hopefully be added soon.
