Apple's iPod Touch comes in three different sizes such as: 8 GB, 32 GB and 64 GB and is similar to the iPhone in both appearance and function wise. Because it has a large amount of storage capability, you can use it as a removable hard drive for your files. Earlier editions of the iPod allowed you to use the player as a hard drive, but the Touch no longer allows this; however, you can still accomplish this using third-party software.
1). Download and install TouchCopy to your computer (see Resources). TouchCopy is not free, though it offers a free trial. TouchCopy works with all models of iPod Touch, and allows you to transfer data back and forth from your computer, whether Mac or Windows, to your iPod as if it were an external hard drive. Installation is straightforward; download the .dmg file for a Mac, or the .exe file for Windows, double-click it and follow the on-screen instructions to install the software.
2). Tap the "App Store" icon on your Touch, and type "Discover" in the search box. Choose the first free app categorized under "Productivity." Download and install Discover to your Touch by following the on-screen instructions. Discover is a free app that allows you to transfer files to and from the iPhone and iPod Touch over a Wi-Fi network. It also allows you to access public and private servers on the Internet with the same devices.
3). Download and install iPhoneBrowser to your computer (see Resources). This is another free open-source application that allows you to browse the Touch as if it were a regular external hard drive.
