zip mime types, when to pick which one

numone picture numone · Dec 10, 2010 · Viewed 27.1k times · Source

So far for Mime Types for Zip files I've seen:

  • application/octet-stream
  • multipart/x-zip
  • application/zip
  • application/zip-compressed
  • application/x-zip-compressed

I guess my question is which is the "best" and why? Why is there so many choices? I use winrar and it doesn't seem to care what the Mimetype is, but WinZip seems to only like multipart/x-zip and application/octet-stream. is there a Mimetype I can have all Zip files be downloaded as that will work in all programs?

thanks!

Registered with IANA MIME type is application/zip : http://www.iana.org/assignments/media-types/application/zip

WinZip is not a reference implementation (since originally ZIP standard is developed by PkWare).
