In hrbrmstr/wand: Retrieve Magic Attributes from Files and Directories

Description

Uses an internal database of over 1,800 file extension-to-MIME mappings to return one or more associated types for a given input path. If no match is found, ??? is returned.

Usage

guess_content_type(path, not_found = "???", custom_db = NULL)

Arguments

path	path to file
not_found	MIME type to use when the content cannot be guessed by file type.
custom_db	a single data frames each with two columns: mime_type and extension. These sources will be used along with the built-in sources and will take priority over the built-in sources. Note that the extensions should be lower case as they are in the official MIME database.

Value
