Can you attach a zip file to an email on the iPad or on one of the Android tablets?
In short: Yes.At length:As Daniel Morgan mentioned, iOS requires this kind of support to be built into individual apps. You will need to use an app (like GoodReader: http://itunes.apple.com/us/app/g...) that supports sending emails with zip attachments. This functionality is not provided by the default Mail application included with iOS. If you compose an email using Mail, there isn't an option for attachments. To send a photos, for example, you need to open the Photos app, tap the "action" button, select your photos, and then tap the "email" button.If you're interested as to why this is the case, then the best answer can probably be derived from a Steve Jobs quote at WWDC 2011:We’ve been working for 10 years to get rid of the file system.(for more context: http://thenextweb.com/apple/2011...)From a user's perspective, the iPad doesn't even have a file system. So you can't go find a zip file, tap it, and send it to someone - unless you have an app specifically built with that functionality included.Surprisingly, Android isn't very much different from iOS in this regard. Your typical off-the-shelf Android device (eg, Droid Incredible) does not include a file browser. Like iOS, you can install 3rd-party solutions to fix this. One popular such app for Android is ASTRO (https://market.android.com/detai...).
