A tool for effective usage of Windiff.

Sample screenshot


File comparing is one of the indispensable tasks of programming, especially if you're modifying someone's code or want to see what changes you've made between the two versions of your programs. Although being an old tool, Windiff is one of the most popular file comparing tools for Windows platform.

One major drawback of this tool is; if you have two files (or directories) to be compared that are in different locations, you either have to browse each of the items through the Windiff's Open File dialog, or copy both of them to the same directory in order to drag them into Windiff.

My solution to this problem is this tiny tool that you can drag and drop files on it and press one button to make Windiff compare them. (Provided that you inform the tool about Windiff's location before.)

Using the code

The source code is very small and self-explanatory. You just take two file names as input and launch an executable by supplying these file names as command line arguments to the program. All of the settings the tool uses is stored in the registry.

Points of Interest

You should first locate Windiff executable from "Options->Locate Windiff" menu item. You can give additional parameters to Windiff from "Options->Parameters" menu item.
