/etc/mime.types is the file in which system-wide rules are defined for mapping filename suffices to MIME types.
Each line in the file is a MIME command:
- Lines starting with a hash # are comments.
- Command lines have a MIME type as their first argument and the rest of the line is blank or contains a MIME descriptor. For instance, here file suffices are mapped to MIME types:
