Recommendations to others considering Examdiff Pro:
ExamDiff Pro is much better than free solutions and well worth the cost if you compare files or folders more than once or twice a week.
Most version control systems let you specify external comparison programs, and I use ExamDiff Pro for SVN and CVS comparisons. Review collected by and hosted on G2.com.
What problems is Examdiff Pro solving and how is that benefiting you?
I use ExamDiff Pro to show changes in files before checking them into version control.
I use it to compare copies of folders (copied for backup purposes, or to a different computer, etc.).
I use it to compare versions of files after other people work on them.
I use it to compare log files produced for debugging (excluding parts of lines helps a lot here). Review collected by and hosted on G2.com.
