File comparison in computing compares the contents of computer files, finding their common contents and their differences. The result of the comparison may be presented in a graphic user interface or as part of larger tasks in networks, file systems, or revision control.
Some widely-used file comparison programs are diff, cmp, FileMerge, Araxis Merge, WinMerge, Beyond Compare, and Microsoft File Compare.
Many text editors and word processors perform file comparison to highlight the changes to a document.

Famous quotes containing the words file and/or comparison:
“Probably nothing in the experience of the rank and file of workers causes more bitterness and envy than the realization which comes sooner or later to many of them that they are “stuck” and can go no further.”
—Mary Barnett Gilson (1877–?)
“In everyone’s youthful dreams, philosophy is still vaguely but inseparably, and with singular truth, associated with the East, nor do after years discover its local habitation in the Western world. In comparison with the philosophers of the East, we may say that modern Europe has yet given birth to none.”
—Henry David Thoreau (1817–1862)
