If you are fond of downloading large image files then you know about mounting software. You would be able to deal with the things that you need to do in terms of reading this type of files. The only way to do this is to use a mounting software. This software acts like a virtual optical drive that is able to playback virtually created optics. This is applicable when you have software created in virtual optical media like image files and other archiving formats. The software allows you to directly open the file without having to resort to extraction or unzipping as it is popularly known. Your process is actually cut down to one single step instead of two.
