How to structure compressed files, such as rar, zip format？

[NLPOR]

I found that when parsing compressed files, the content of each file in the subdirectory is mixed in the content field. eg. test.zip => test/a.txt test/b.txt, after parsed = parser.from_file('test.zip') parsed['content']=..... parsed['metadata']=...... How can I structure the file ‘content‘ and ‘metadata‘ in the subdirectory according to the file name of the subdirectory?
