When I submit my research papers to an online review system, I prefer to upload all files (manuscript, figures, etc) by a single zip file, so that the review system can unzip the file. Otherwise, I have to upload many files one by one; time-consuming.
However, if I create a zip file using the Mac OS X's native Compress functionality, the review system tells it may be a corrupt file. Every time I try, it does same.
Instead if I use
zip command in Terminal to create a zip file, it is fine.
What kind of zip technology does Compress use? Anything non-standard? Do you see any potential reasons for the fails?
