I switched to Mac last year. I now own a MacBook and I am loving it. But I am experiencing a problem. My drive is only 80GB and it is near capacity. I have an external drive and I drag and drop files to the external in order to make room on my HD. The problem occurs when I open the files on the external later on. For some reason, my Mac places the files back onto the HD, defeating the purpose of using the external in the first place. I am not that computer savvy, but I never had this problem before with Windows. I know there has to be a solution; it's a Mac.
