What mime type should I use for CSV ZIP files?

Question

I am trying to send an email using Simple Java Mail API. The email will contain a CSV ZIP file attachment. Should I use text/csv or application/zip for the mime type of the attachment?

Answer 1

A zip file is a zip file, no matter what it contains.

It should be application/zip.

It is not a CSV file, if you tried to parse it as CSV it would fail. It is not text/csv.

Answer 2

In linux, you can find way much of the in the following file: /etc/mime.types. See below to find out what mime is suitable for zip files.

grep zip /etc/mime.types
