I know tar.gz is not listed as one of the supported formats, so I don’t expect it to work (although it would be nice), but I do expect a FileTypeNotSupportedException to be thrown.
It’s not hugely important for us, but I noticed that the content is missing/incorrect when rendering a gzip archive. Render GZip Archive.zip (15.0 KB)
I does render the archive name properly “Compressed Word File.gz” but shows the content is “Compressed Word File”. If you open the archive, you will see the content is actually “Portrait_Landscape.docx”
