Reads Attributes
Name Description
mime.type If the <Packaging Format> property is set to use mime.type attribute, this attribute is used to determine the FlowFile's MIME Type. In this case, if the attribute is set to application/tar, the TAR Packaging Format will be used. If the attribute is set to application/zip, the ZIP Packaging Format will be used. If the attribute is set to application/flowfile-v3 or application/flowfile-v2 or application/flowfile-v1, the appropriate FlowFile Packaging Format will be used. If this attribute is missing, the FlowFile will be routed to 'failure'. Otherwise, if the attribute's value is not one of those mentioned above, the FlowFile will be routed to 'success' without being unpacked. Use the File Filter property only extract files matching a specific regular expression.
