This app works flawlessly. I kept receiving "winmail.dat" attachments from clients that I couldn't open on my device, but this app reads them perfectly every single time. It extracts files and opens text instantly without any formatting issues. The interface is clean, straightforward, and saved me so much frustration. It is a must-have tool for work!
