I've never seen a significant reduction in file size by doing so, and if there's the risk of corruption in the process. In the future I will never archive files again. Now I'm developing my portfolio and there are a few works from that file that I need to include. The idea of "archiving" to me meant that I was basically boxing them up for use at some later date, but not something I had any intention of accessing on a regular basis. I archived them in the first place, because they were files that I generated in a previous year here at university and needed to archive. None of them had worked and fail with an error message of their own that equates to a possible corruption issue. I have tried stuffit expander and a couple of others to see if there would be any change in the lack of success with unzipping the file.
