What is a program that opens any file?

There is no program that can open any file. There are so many different types of files that such a program would be virtually impossible. Even if such a program were to exist, it would take up terrabytes and terabytes of space on you computer (Assuming, by some miracle, that your computer even has so much space) and would be extremely, painfully slow. If you need to find which program to open a file with, try this:
  1. Change you computer setting to show file extensions. You may need to look elsewhere to find how to do this on your operating system, but on windows 7 it's under Start (looks like a little flag in the bottom left-hand corner of the screen), then control panel, appearance and personalization, in folder options, under the view tab. Uncheck "Hide file extensions for known file types.
  2. Look at the file you are trying to open. There should be the file's name, followed by a period and then a small group of letters (usually 3, although sometime there are more or less). This is called the file extension.
  3. Go to link below and type the file extension of the file you are trying to open. It will give you a short description and a list of programs that will open that file. If you have one of those programs, you can use it, otherwise you will have to download/buy one of the programs on the list.
