If you have an iPhone or iPod Touch, then you will welcome this light program called Diskad.
DiskAid is an application to transfer iPhone or iPod Touch files from a PC, such as it is a common hard disk.
If you only have to run it and then plug the device. The computer will detect it as removable HD and you'll be able to act as normal
But diskaid is not the way to transfer music from PC to iPhone. You will need iTunes or similar software to do it.
Get the most out of your iPhone / iPod Touch using DSPAid.
