    Dim wordDocument As Variant
    wordDocument = z.UncompressFileToMem("faxCover.doc.Z")
    z.WriteFile "faxCover.doc", wordDocument
    ' We could have simply done this:
    z.UncompressFile "faxCover.doc.Z", "faxCover2.doc"
    
    wordDocument = gzip.UncompressFileToMem("faxCover.doc.gz")
    gzip.WriteFile "faxCover.doc", wordDocument
    ' We could have simply done this:
    gzip.UncompressFile "faxCover.doc.gz", "faxCover2.doc"
