Utility for Text File Comparison

Can someone please recommend a good utility to compare text files for differences?

I have a series of sample input files and after editing the source and rebuilding the EXE, I run each sample input and check the output for unintentional changes versus the prior version. A compare utility would make the task much easier and more accurate.

Thank you.

A very good tool for file comparison is:

I use WinMerge. Plato has some limited file comparison functionality.

cmd.exe's FC provides a text comparison facility, as a text report summary. The best ones are graphical displays that split the screen and colour the differences. I use to use ED for Windows Ver 3.8 which used bold colours to highlight the differences and allowed editing and updating the difference display, but sadly it was a 16-bit program that I lost at Windows 7. There are newer utilities available, but all that I have seen miss the point of the comparison, which is you want to clearly see and step through where the changes are.

Quoted from JohnCampbell There are newer utilities available, but all that I have seen miss the point of the comparison, which is you want to clearly see and step through where the changes are.

I use Beyond Compare and think it does the job really well.

Here is a screenshot showing changes in my old project.

ExamDiff Pro is working under Windows 7 and shows the differences between both files very clearly:

Same beauty and simplisity as above with Total Commander. Windows is not usable for me without it. I run 5 different color TC simultaneously (and could be even more when I switch to 4k monitors) which are doing many other useful things
