• @Hirom It really is one of the most popular archive formats on Windows. Because of WinRAR. In fact, the popularity of the formats on Windows seems directly proportioned with software usage over time (i.e. WinRAR, WinZIP - where zip is now native since a long time - 7-zip etc.)

    tar.gz et all are really just alien for the vast majority of Windows users, especially the non techie ones.
