Morphology
The meaning (the characters added to a file's name that indicate its type) is directly compositional from 'file' (the item), 'name' (its identifier) and 'extension' (an add-on or ending). This follows a transparent noun-modifier pattern commonly used in computing and is cross-linguistically regular, so a B1 learner who knows the constituent words should be able to infer the meaning.
Etymology
File name extension comes from the simple idea of adding a small tag to the end of a file name, where the extension is like a short tail often starting with a dot. So, it tells the computer the file's 'type' and which 'program' can 'open' it.
