Apple .PAGES documents

I see that LibreOffice v5.2.4 has the ability to open “Apple Pages 4” documents. A friend received a 756KB file via email and did not know what to do with it. She has both LO and MS Office.

I tried opening it in LO v5.2.4 but there was no relevant content.

I went to CloudConvert and was able to convert it successfully convert into a MS Word Document ( .DOC ) file.

Is there an improved PAGES file format Extension in the Library of Extensions ?

Is there something else that can be done in LO for current .PAGES files ?

Is there a Meta Data tag that identifies what .PAGES format the document is in ?
