WinFC is a utility that allows the owner to compare the contents of 
two or more files. The comparison is done line by line and the output 
shows how and where the files differ.

WinFC provides an easy to use interface giving the owner direct access to 
the DOS FC command while remaining in the Windows environment.  By using 
WinFC, opening a DOS prompt window or exiting Windows is no longer 
necessary. The user can generate a record of file differences for as many 
files as they want with a few simple mouse clicks or key board strokes.
A registered version will install a new menu option in the Program Manager.

DOS 6.0 or higher and Windows 3.1 are required.
