Morphology

file + allocation + table

The phrase is fully compositional: 'file' (items stored), 'allocation' (assignment of storage), and 'table' (a recorded list) combine to mean a table listing how storage is assigned to files. Although technical, the function of the term follows ordinary noun-compounding logic, so a learner who knows the constituent words can infer its meaning.

Etymology

File allocation table is like a simple table that lists where each file sits on a disk and which areas are bad. The word allocation means giving space, so this part 'keeps track' of where files are stored, which is why the name describes its job.
