I can zip a folder so that it maintains its folder structure. That isn't the problem.

I want to be able to batch zip more than one folder at a time so that I don't have to sit there and right click over and over again for each zip I want to make.

When I use BatchZip Tool Kit for zipping up .png files, I just select all of the individual .png files and let BatchZip go down the list and zip up each file. i don't have to sit there and right click each .png file and zip it one at a time. It's done as a batch process.

I want to be able to do the same thing with my folders so that the subfolder structure is maintained

For example. I don't want to have to click on Runtime1 and right click on Geometries and zip it, then right click on Textures and zip it, then go into the Library folder and right click on each of the character, props, poses etc folders to zip those.  I would like a way to select all of the folders that I want to zip, then have the program go down the list and zip them up while maintaining the folder structure of each  of the main folders it's zipping

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
