complete list of mime-type <-> file extension mapping

Question

I can't find a complete list of mime-type mappings on the internet. I would like to have a list that refers a file extension to every existing mime type.

The list of all mime-types can be found here:
http://www.iana.org/assignments/media-types

but that resource doesn't include the file extension mapping.

I googled a while and couldn't find a mapping list with all mime-types. Only lists with most common ones. In all lists I found for example this entry is missing:

application/vnd.openxmlformats-officedocument.wordprocessingml.document   ->  .docx

Does someone know a resource where to find a complete mapping?

Answer 1

Using Jürgen's mime.types link and a little command line magic, you can generate the list you want very quickly:

wget -qO- http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types | egrep -v ^# | awk '{ for (i=2; i<=NF; i++) {print $i" "$1}}' | sort

Answer 2

You have to install apache or nginx or something else and look at the mime.types file.

# MIME type                 Extensions
# application/3gpp-ims+xml
# application/activemessage
application/andrew-inset            ez
# application/applefile
application/applixware              aw
application/atom+xml                atom
application/atomcat+xml             atomcat
# application/atomicmail
application/atomsvc+xml             atomsvc
# application/auth-policy+xml
...
more, more, more over 1300 mine-types.

I just want to let you know, there is a new class for this in framework 4.5

System.Web.MimeMapping.GetMimeMapping(filename);
