Why Beyond Compare tool rocks

If a picture is worth a thousand words, here’s 10K worth for why you should check out Beyond Compare. It’s the one tool that I use every day I’m working at my computer. I’ve used it to compare not only files and folders but zip files to folders - it treats a zip like a folder and let’s you update the zip in situ. I’ve also used it to compare two Word documents, two Excel spreadsheets, MP3 files (tags), version stamps on executables. However, I wasn’t aware it could compare two photographs and show a “mask” of the differences between them!! It’s also the “external” tool I use for differencing in version control systems. If you earn your living using a (Windows or Linux) computer, how can you not afford to spend $50 to increase your productivity?
