In general semantics, extension is a process that, as in this mathematical example, starts with unique individuals, and gives them unique names, e.g., I, II, III, etc., or 1, 2, 3, etc. The next step if needed generalizes or passes beyond extension to infinite-valued higher-order abstractions like 'numbers', and so on. The passing from lower-order abstractions (presented extensionally) to higher orders, e.g., from '1, 2, 3, etc.,' to 'numbers,' is said to follow the 'natural order of evaluation,' so that when one talks about order, extension is implied, and when one talks about extension, order is implied. An example of reversed order is when a particular higher-order abstraction such as race, e.g., 'white', 'black' etc., is projected onto the individuals comprising it. The individuals (each uniquely different by extension, no matter what is being discussed) comprise the 'race' (which exists only on higher-orders), not the other way around. See extensional devices.
In mathematics, an extension of some structure is another structure which contains the original structure.

Continuous extension may be described as that property in virtue whereof the parts into which material substance is divisible are situally arranged in orderly relation one beyond the other (internal and potentially local extension) and hence are naturally commensurate with the corresponding parts of the immediately environing surfaces (external and actual local extension).
Probably the more general opinion is that extension radically and essentially consists in the internal distribution of the parts into which matter is divisible, and that external extension, or the correspondence of those parts to the parts of the locating surfaces, is a sequent property of essential or internal extension.
Continuous extension is an objective property of matter, not a mere mental form moulding the sensuous impression produced in the sensory organs by some sort of physical motion.
A filenameextension is an extra set of (usually) alphanumeric Generally speaking, the term alphanumeric refers to anything that consists of only letters and numbers.
Filenameextensions have been in use for decades, but they have gained common usage because the file systems file system is a method for storing and organizing computer files and the data they contain to make it easy to find and access them.
Mapping filenameextensions to content-types is then done using different heuristics, such as examining both the filenameextension and the contents of the file.
