the.com/file

means a collection of related data stored under a single name on a computer, or a folder/document holding physical papers, or the act of submitting or arranging such things in order.

from From Latin 'filum,' meaning 'thread' — and the thread is the whole point. Officials once kept documents in order by literally stringing them on a wire or thread, so 'file' first meant that thread of papers. The word passed through French 'filer' (to spin, to thread) into English, where the line of strung documents became the orderly collection itself. The 'file' as in nail-file is a separate word entirely, from Old English 'fēol,' a tool for smoothing — a coincidence of spelling, not a shared root. When computing arrived, the threaded-papers sense leapt naturally to the digital container, keeping the old idea: things gathered in order under one heading.
