I have trouble understanding file formats, or maybe I have figured it out. Please help me!
A file format is a specification that tells how the data of a file is arranged and thus how it is to be interpreted. Does this mean, for instance, that data arranged according to a JPEG (an image format and codec) will tell my computer that the data is to be interpreted as an image?

Think of it if the file is like a screw or bolt. The file format is like the top of the bolt that tells you what bit to use – Phillips, flat head, star, hex, etc. You can’t turn the bolt unless you know what type it is.
The computer can’t open the file unless it knows what type of file it is.
