Watch Directory can save you a lot of time due to the fact that repetitive tasks can be automated. With its large array of options, you can create any task in a flexible way.
When creating a new task, the wizard's many options can overwhelm a novice user.
You can forget about performing the same task over and over again. This can be done automatically by Watch Directory's features, saving you valuable time...."
About the Cons. I have to agree. WD is not for people who just started to use a computer. It is hard to implement lots of functionality and maintaining usability. I wonder how Frederick would review WatchDirectory v1.0, years ago... No wizards, only a command-line program.
