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?

  • Another difference is: the Mac compressed zip contains some .DS_Store files and possibly other files invisible on the Mac but not invisible in Windows.

As its man page states,

The compress utility reduces the size of files using adaptive Lempel-Ziv coding.

In contrast, the zip command (also present in Mac OS X, at least in Mountain Lion) uses a different algorithm. If a publisher is expecting a zip-compressed file, a file compressed with compress is something different, and will not work for this.
