The PCMACLINK2 USB (Universal Serial Bus) to USB (Universal Serial Bus) data transfer cable offers direct file transfers via USB (Universal Serial Bus) connection between two computers (PC & Mac, PC & PC, Mac & Mac). The USB (Universal Serial Bus) data transfer cable eliminates the complicated network setup required to transfer files between computers, or the need to use external storage devices to transfer files back & forth, saving time & hassle. Once the cable has been connected, a built-in software suite will automatically install on each computer, which not only creates a convenient path for the file transfers but also means that you can sync e-mails from Microsoft Outlook, synchronize the contents of entire folders, or even share CD/DVD drive access & an Internet connection (between two Windows-based computers). Only supports Mac up to v 10.5.
