The mimemap file

mimemap specifies the file name extension to MIME type mappings.

For file names without an extension, or with an unknown one, the system's file -i command will be executed to determine the MIME type (this can be switched off inside the main configuration file).

The mappings can be specified on a per-subtree basis, which may be useful in some cases. Example: gaim logs have a .txt extension but should be handled specially, which is possible because they are usually all located in one place.

The recoll_noindex mimemap variable has been moved to recoll.conf and renamed to noContentSuffixes, while keeping the same function, as of Recoll version 1.21. For older Recoll versions, see the documentation for noContentSuffixes but use recoll_noindex in mimemap.
