I made couple converters for myself that others might find usefull too.
Link Converter
Link converter loads the shortcut target file for comparison. So instead of showing the data of the actual shortcut (.lnk) file, the data of the file that the shortcut file points to is shown in Compare it!.
URL Converter
URL converter is like Link Converter for .url files. It downloads the file that the .url points to from http or ftp server.
