Good app!

WinMerge is absolutely indispensible ā not only for developers. If you are just a regular computer user and realize that your colleagues have created several copies of a file (or even a whole folder), WinMerge helps you quickly find the differences (if any).

I am a utilitiophile. And I have a core group that I keep close at hand because they just work, they perform specific tasks and they make my life better. I can go on about how much this has improved since Gen-Zero, but all that is unnecessary. I find it invaluable.

Thank you very much for the free open source program!

I have been using Notepad++ for years along with certain plugins I thought I could not do without. I had been using the compare plugin for Notepad++ and have always found it clunky and hard to configure to where it makes any sense at all. Someone suggested WinMerge and all I can say is WOW. This is exactly what the Notepad++ Compare plugin should be. From this point forward I will be using WinMerge when it comes to comparing large documents. I send out weekly price sheets for refurbished systems and these documents change from week to week. WinMerge has made updating the latest pricelist easy as can be, whereas before it was a HUGE problem using Notepad++ compare. I went from 30-40 minutes making changes to less than 5 minutes making changes. That's a timesaver and believe it or not time really is money.
