Security Options
WordPress recognizes the file mime type by finfo_file function (wp-includes/functions.php). However, sometimes, the standard MIME type of a file and the MIME type of a WordPress-recognized file are different. By enabling both this option (in setting menu) and the “Enable the attempt to determine the real file type of a file by WordPress core.”, the file type is displayed if it is from Media. PLEASE keep in mind that a file uploads are stopped while they are being processed if the both of two options are enabled. Therefore, be sure to disable this debugging option after debugging.
If the added mime type does not work, please deactivate other mime type plugins or the setting of other mime type plugins.
For example, if you install Media Library Assistant plugin, please turn off “Enable Upload MIME Type Support” in the Upload tag in this plugin setting.
Yes. The function was supported by Version 2.4.0.

ex. XXX.YYY.ZZZ — sanitized –> XXX_.YYY.ZZZ — fixed the plugin –> XXX.YYY.ZZZ
In detail, please see sanitize_file_name function in “wp-includes/formatting.php”.
