Drag & Difference

Dragdiff.dll is a drag and drop shell extension. If a file/directory is right-dragged to a directory, the option WinDiff will start windiff, comparing the two directories, or comparing the file to a file by the same name in the target directory.

WinDiff must be on the search path.

Dragdiff can be installed by right-clicking on dragdiff.inf and choosing install. It can be uninstalled with the Add/remove Programs control panel applet.

You must be an Administrator to install shell extensions on Windows.
