My Kingdom for a Good Diff

With all the coding playpens, browsers powerful  Element Inspectors and the availability of great debuggers in Eclipse, CodeLobster and NetBeans, one can easily forget how useful a Diff file comparison utility can be. And now that JavaScript and SQL, and CSS code starts to run into hundreds of lines and team connections can mean several versions of the “latest file” – diff has become a more pressing need in the past few months.

Presto, for Windows developers there is a mighty fine free solution from PrestoSoft:
difftool
Typical multi-hundred line diff result

As noted ExamDiff  handles diffs for files with hundreds of lines of code almost instantaneously. As users pass into thousands of lines of code and multiple files they may want to upgrade to ExamDiff Pro which is well worth the price of  $35US  for the time saved in larger systems. What makes ExamDiff so handy is that it can compare just about any text file in different directories, invoke an editor of your choice to update  the file in either Window pane,  and quickly jump  from each difference point in the two files. In short a visual Diff the way you would implement it. Highly recommended.
