Filename Extensions

A filename extension is a suffix separated from the base filename by a period. It is applied to the name of a computer file to indicate the encoding (file format) of its contents.

In Veeam technical documentation, we write filename extensions in upper-case letters following a period — non-italic, non-bold and non-underlined.
