I guess it's pretty safe to assume everybody knows what a file is (but many have trouble explaining it). So let's quote an abstract from Wikipedia:
A computer file is a resource for storing information, which is available to a computer program and is usually based on some kind of durable storage.

A group of files used by the same program can be packed into one archive file.
