IBM Connections Cloud customers can configure Email Filters in the Account Settings / Email Filters
Recently (end of March) those filters have been updated with a new feature to filter attachments cased on a certain type.

But what exactly are the file types that are being filtered when you enable this feature for a specific category?

IBM Connections Cloud is using IBM (Lotus) Protector for Mail Security, which allows to filter attachment based on mime types.
Attachment categories displayed here relate to the media type analysis module of IBM Protector which describes in detail which file types or file extensions are being filtered.

Here is a more detailled list of file types in each category.
Please note that this list is going to change in the future so I can not provide any guarantuee for completeness.
