MLCP command options to export a binary file

I want to export a binary (PPTX) file stored in MarkLogic to my local file system. Is it possible to export a document stored in a URI through MLCP EXPORT?

There are millions of documents stored in the same directory - so MLCP EXPORT with -directory_filter option is of no use. The export operation begins and errored out with "RequestException instantiating ResultItem 141931: Time limit exceeded".

This is my options file

-host
marklogic-dev-server
-port
9014
-username
pk
-password
pk
-directory_filter
/openxml2/
#-query_filter
#doc("/openxml2/doc-uri.pptx")
-output_type
archive
-output_file_path
/Users/pk/marklogic/
-compress
true````

MLCP by default will export the document in it's native format:

Use the mlcp export command to export documents in their original format as files on the native filesystem or HDFS. For example, you can export an XML document as a text file containing XML, or a binary document as a JPG image.

For example, you can export an XML document as a text file containing XML, or a binary document as a JPG image. There are a number of different ways to limit the documents exported by MCLP. You should be able to use -query_filter, -query_options or -document_selector to select the file by itself.

Alternatively, you can add the document to a new collection, and use -collection_filter. This is ok for a small number of documents, but not advisable for a larger set, as adding a collection to a large number of documents can be resource intensive.
