I am currently leading a small team of developers and we are reaching the final stages of a major project for a very important corporate client. Before we hand over the keys, we need to ensure that the end-users don’t experience a total system crash if they accidentally upload a damaged document.

I am looking for a reliable file corruption tool for UAT testing to simulate these real-world user mistakes during our final walk-through. It is crucial that the interface remains stable and provides helpful feedback to the user rather than just freezing up. Does anyone have a favorite utility for this?

Thanks in advance.
