The 7Z format was first introduced in down10.software/download-7-zip 1999 and grew in popularity as an improvement upon the more common ZIP format. The 7-Zip file archiver is typically used to create 7Z files, but the files may also be created by other compression utilities, such as PeaZip and PowerISO. Users can extract files from RAR and ZIP folders. This can be done by right-clicking on the folder to access the context menu as well as in the application. Within the shortcut menu, you click on ‘Extract Here’ to pull the file into the same area as the compressed folder.
