I recently purchased a MBP 13" i7 and it has been a wonderful experience. For the past week or so, I have checked the hard drive data, and found that it keeps growing. Now it reads "6.83 GB free of 499.25" and the entire hard drive is filled with "other" in yellow. I only had a few Gb's of music, documents, and pictures from my old computer, and I do not know what this "other" is or how to deal with it. Any suggestions on how to resolve this issue?
