Visual File Compare

Visual File Compare (or VFC) is the small utility for two files comparing in visual mode that represents results of compare in two windows on screen side-by-side or up down where parts that matches and part that differs shown on different colours.

Comparing can be text where files represent as text line by line, or binary where dump representation of information used. This utility is for DOS32, Win32 (Windows 9x, Windows NT or Windows 2000 console mode) or OS/2 (version 2.11 or later VIO or Full-screen mode) environments. There are two modules, VFC.EXE for DOS32 and OS/2 (DOS mode needs DPMI server like CWSDPMI) and VFCW.EXE for DOS32 and Win32 (DOS mode need 32rtm DPMI server from Inprise).

This utility is an excellent tool for comparing source files of programs in Assembler, C, HTML, Pascal etc., or reports from databases to search differences between versions and for correction aids. For example, the task of search differences between config.sys and config.bak after install process to some product to understand modifications this setup makes to your system. Lot criteria of comparing (case sense, white spaces elimination, sync length and more ) makes compare very effective. Some file managers can use this utility inside, we know this about XtreeGold and ZtreeBold, because both of them have internal file compare command that calls an external utility.
