Military air marshallers use hand and body gestures to direct flight operations aboard aircraft carriers. A gesture is a form of non-verbal communication or non-vocal communication in which visible bodily actions communicate particular messages, either in place of, or in conjunction with, speech. Gestures include movement of the hands, face, or other parts of the body.
I recently download an installation file as an ISO. I have installed DAEMON Tools, and tried to open it by mounting it. But it didn't open. I tried Alcohol too. The file is 6GB.
Many applications that can be used with ZIP files can also be used with ISO files, so you may already have such an application available. Your application might use the word decompress rather than extract or unzip, but the result is the same. You need additional software to extract an ISO file.
