Frequently Asked Questions

Common questions about Add MIME Types

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. WordPress sanitizes the filename in case of 2 or more extensions. ex. XXX.YYY.ZZZ --> XXX_.YYY.ZZZ. The plugin fixes the sanitized extension when a file is uploaded in the media in case of allowed extensions. 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".

Yes. You can comment out above version 2.3.0.

Yes. WordPress core has implemented the security check for a file content since version 4.7.1. The plugin's default setting disables this security check .

The setting in the multisite network administration dashboard is taken precedence. The setting in each site administration dashboard is displayed, but the values aren't applied.

The setting values in each site administration dashboard in case of activating the plugin in each site is applied.

Yes, each setting values are saved as the other setting items.

Yes, it is available on the version 3.0.0. If the head in each line is set to '-', then the MIME type restricts. ex. -bmp = image/bmp The files which has "bmp" file extention becomes not to be able to upload.
