PSPad is a freeware code editor for developer which can be installed in Microsoft Windows Systems. It’s a freeware editor which is useful for developers to find out Text Differences, not only finding out Text Differences but it has got many features like this is an useful tool for the people who work with plain text, this editor has good formatting functions, which includes a spell checker, we can create web pages very easily and can be used as a good IDE for compilers, PSPad catches and parses compiler output, integrates external help files, compares versions and many more features.
This tool is a fully tested tool and was tested in Softpedia labs, I would like to recommend this tool because recently I was handling one of the project in which for one of the file I made some changes long back but I could not remember where I made those changes with the old file. So just I opened the respective old file first and through the menu option (Tools -> Text Differences -> Text Diff with This File…) I have opened the new file and compared the respective changes very easily and integrated the code accordingly in the new file, my job is done. I do agree that there might be some tools which does the same job but I would like to recommend it as it is a freeware product both for personal and commercial use and it does not contain any malware.
