ExamDiff Pro 4.0

ExamDiff Pro is a visual comparison utility that shows you the
line-by-line differences between two text files, and lets you
compare the contents of file directories.
You can easily navigate through the differences and visually
compare the two files. A handy re-compare function leaves your
focus in the same place as before the re-compare.
Features of ExamDiff include: the ability to save differences
in a standard UNIX DIFF file, easy editing of either file
in your favorite editor, a search command, customizable
display options, drag and drop support, an adjustable pane
splitter with smooth synchronized scrolling, and command line
options.
This 'Pro' version also lets you compare directories and
perform basic file management functions, including copying,
renaming, and deleting files or directories.
This newest release highlights differences all the way down to
the level of words or characters in changed lines. You can now
print (and print preview) the diff report. A command-line
option has been added which allows the results to be sent to a file.
