Quote - I used WinAce and did batch zipping with it with no problems.
But those where small batches, the freebies I made.
I dont know how it handles huge files.

Yeah, I know I can't really zip a whole runtime into one zip file. What I'm actually doing is making several zip files for each runtime:

Geomettries
Textures
Either the whole Library depending on which runtime, or each folder (IE: characters, props, poses etc)  in the top level of the library.
But what Batchzip has been doing is zipping every single folder inside the Geometries and Texture folders, and if those tolders had sub folders in them, zipping those up separately.  So instead of my having to unzip a few zip files, I would have to troll through folder after folder to find all of the hundreds of zip files that Batchzip is creating.

heart whatever they might have to say." - Ghandi
