The UI is very intuitive; it's easy to use. I like how easy it is to use as well as how many different features there are. It's also free! I dislike how slow it sometimes gets when I'm trying to do things like copy large files. I've had problems with this in the past but have not encountered it recently. If you're looking for a simple program that lets you access sites via FTP without too much hassle then this is what you want. I used to use Filezilla. But after having trouble with it I switched over to FTP Explorer. It's been great so far. I am able to get my work done more efficiently than before.
