WinDiff (Windows SDK core SDK Tools)

Compare the contents of two files or sets of files with a graphical interface.

      windiff [path1] [path2]

    path   Individual files to compare or a directory of files to compare.

If either path is not specified it will default to the current directory (or a matching file in the current directory)

If nothing is specified, the GUI will appear - select files to compare with the menus.

White background = parts common to both files.
Red background = parts that belong to the file listed on the left .
Yellow background = parts that belong to the file listed on the right .

Registry files (exported with regedit) can also be compared. Also see the help file Windiff.hlp.

Originally part of the Microsoft Windows 2008 SDK it can now be found via Grigsoft (3rd party mirror) WinDiff (75 Kb).

"Shall I compare thee to a summer's day? Thou art more lovely and more temperate.
Rough winds do shake the darling buds of May, And summer's lease hath all too short a date" ~ Shakespeare
