As we know, Apple does not allow users of its devices to connect external storage, thus making it impossible to connect to theiPad devices with attachment USB as hard disk or pendrive to transfer files between devices. This does not mean that the connection cannot be made, but who owns a Apple device with Jailbreak, this possible. It's true, if your jailbroken device, you can connect a pendrive or a hard disk to your iPad that allow you to transfer files between the devices in an easier and faster way.
What you need to connect to your iPad is a pendrive obviously an iPad with Jailbreak, an accessory calledCamera Connection Kit(here you can buy the model compatible with iPad 1,2 and 3, here instead the model compatible with iPad 4, Air and mini) with USB port and a storage device (pendrive or hard disk).
If you have everything you need at hand, you can prepare to enjoy the simplicity of transferring files between an iPad and an external storage device, following the procedures contained in this guide. Let's see how:
The first condition to connect a pendrive to your iPad is to have a iPad with Jailbreak (here our guide).
If you don't wash, you need to download the tweak from Cydia iFile and install it on the iPad.
Now connect the pendrive to the USB port of the Camera Connection Kit and insert the latter into the iPad door.
Open iFile previously installed on the iPad and in the left column appears the connected Drive with all the files it contains.
Click on it to view the files contained in the drive. In addition to connecting pendrives and hard drives, you can also connect keyboards, cameras and everything that does not need the installation of drivers.
I hope this guide has been useful to connect a pendrive or an external hard disk to your iPad to transfer files between the two devices.
