SIS Software's Pocket Drive is an app that wants to make file transfers between your iOS device and your Mac or PC as easy as possible. To do this, it combines a simple file transfer mechanism with a well-rounded file manager, or in other words, your iPhone or iPad becomes a wireless hard drive "with the power of OS X's Finder and the simplicity of Dropbox". Only Pocket Drive is even simpler, because it needs no network connection or initial setup. Just open the app, and your Mac or PC sees the iOS device as an external hard drive. The files on it are managed just like on an OS X or Windows desktop.
There's also a built-in ZIP archiver and a file downloader, which makes it easy to store data inside Pocket Drive when you're away from the computer. The app supports any file type for storage, and it opens over 25 file types for viewing, including the fundamental Pages, Numbers, Keynote, Word, Excel, PowerPoint, PDF, RTF, JPEG, GIF, TIF, MOV, MP4, MP3, and ZIP formats.
If Pocket Drive sounds like your thing, the pricing goes as follows - 512MB of storage are available for everyone in the app's free version, and additional storage is bought via in-app purchases. Meanwhile, Pocket Drive + costs $4.99 and it lets you handle as many files as your free iOS storage can store. Sounds like a fair deal.
