I have an old computer which has files and folders that I want to transfer onto my new computer. My old computer run WinMe and has only a CD-Rom, while my new computer run WinXP Home and has a DVD-RW. I have the possibility to acquire an external HDD. Would it be difficult to transfer files from my old computer onto the external HDD and then to transfer the same files from the external HDD onto my new computer? Or an external HDD is only to have an extra separate storage from your computer? Thank you.
