Hi, I have an IMAC and I am having problems transfering video files I download to my external hard drive. I had trouble playing the files at first because it was not readable with Quicktime. I downloaded VPN and it played with VPN. I dont want to save those files on my computer so I would like to transfer it to my external harddrive. When I try to drag it over, it won't let me drop it in. Is there a simple fix for this? I am new to the MAC world. Is there a way to choose where it will save itself right before you download like there is on windows. I click on it and it does not prompt you, it just starts downloading. Any help would be great. Thanks.
