I have some VERY BIG 200MB RAR File Archives and I can't seem to open them. I have UnrarX and Stuffit Expander on my Mac. Stuffit stalls out and UnrarX tells me: "Unexpected end of archive" What does this mean? Are the RAR files damaged? If so can I repair them somehow. P.S. I also have Windows XP on Parallels Desktop. Would XP solve this problem better?
