If the MIME Type can be identified, an attribute with the name 'mime.type' is added with the value being the MIME Type. If the MIME Type cannot be determined, the value will be set to 'application/octet-stream'. In addition, the attribute mime.extension will be set if a common file extension for the MIME Type is known. If both Config File and Config Body are not set, the default NiFi MIME Types will be used.</p><p><a href="additionalDetails.html">Additional Details...</a></p><h3>Tags: </h3><p>compression, gzip, bzip2, zip, MIME, mime.type, file, identify</p><h3>Properties: </h3><p>In the list below, the names of required properties appear in <strong>bold</strong>.
