This has a virus in it. Very dangerous.
Zipghost 3.71 is an excellent tool. I found this to be the best for batch zip and unzip so far. Easy to use, with easy to understand menu and button options. Ran on well on Vista without any problems so far.
Used for project I needed for a project. Worked well. Am not sure how useful in normal usage.
What I was looking for.. I did a search for a application to do exactly what this program does. I need not look any further.
