Support for this product has ended. There are known problems with this product on recent versions of the macOS; in particular, it is known to trigger kernel panics on some versions of the kernel when Zip files are ejected. This is caused by kernel bugs and the only possible workaround would be to completely rewrite Zipster to work in a different manner.
Ever been envious of the way Windows users can just browse into Zip files, copy files in and out of them with ease and all without running a Zip utility? With Zipster, your Zip files are just like another folder in Finder. Plus, unlike on Windows, you can open files and save into them from any application.
