The WIFI signal in my shop is pretty sketchy so, watching an instructional video out there can be a frustrating experience. I needed a way to grab a video from my PC in the house and take it to the shop. I'm sure there are work arounds for accomplishing this but, not being tech savvy, I needed something really simple. This little program fills the bill. The instructions for using it are very easy to understand. I just grabbed the video needed and stuck it on one of those USB thingies to take to lap top in the shop. It works great.
