Thanks, but this is a little bit different. I have iFile linked to my Dropbox account, so Dropbox shows up in my iFile sidebar. If I click on Dropbox and navigate to the archive I want to extract, I get a popup listing various options, including Zip Viewer and Unarchiver. If I select Zip Viewer, I get a list of files in the archive. I can then select any of those and press the extract button on the lower right of he screen. No where in this process is there any mention of downloading the archive, and the extracted files aren't showing up in any Documents folder I can find. My suspicion is that iFile isn't really extracting the files in this case, even though the process seems to be working. (In other words, I'll probably have to download the archive as you described, even though I actually only want a couple of the files in it.)
