Some problems

I picked this one up, hoping it would resolve some issues, but it disappointed me on one big point: it does not recognize passwords. I tried a couple of different ones, thinking it might be an iPad-related keyboard issue, but even a simple lower case password was not recognized, and it kept asking for it. So it will not open password-protected zip files, which only makes it half-useful. The print in zip box dialog takes forever to show up when I open the attachment in Safari. Initially, I thought it didnt work at all, then I realized it just took a while. So, if your main concern is zipping for file size, and security isnt an issue for you, then this app will work okay. If you need to open password-protected zip files, I doubt it will work - it did not work for me. Hopefully they will fix this bug soon. I need to open secured zips.
