Where can I read about what it consists of, for example, an MP3 file and others?

Question

Programming

In general, all day yesterday I tried to squeeze out a wording from my miserable brain to drive it into the search to see how an MP3 file or AVI file and others were built, but I could not. In general, I want to know how it turns out that the MP3 file is played by the player, how the doc file is saved and unrecognized only on Office and similar applications.

Answer 2

Bytes in files. What exactly are the bytes and what do they mean - google for a request like "MP3 file format"

Answer 3

This is like a file association mechanism - the file has an extension (part of the name, after the rightmost dot), by this extension the file manager will know which program to run and which icon to show.
