The code to parse the FILESHARING record does not seem to take account of
changes from BIFF5 to BIFF8. Here is an extract from the openoffice xls file
format document:
0 2 1 = Recommend read-only state while loading the file
2 2 Hash value calculated from the read-only password (➜4.18.4)
4 var. User name of the file creator
BIFF2-BIFF5: Byte string, 8-bit string length (➜2.5.2)
BIFF8: Unicode string, 16-bit string length (➜2.5.3)
170
A trivial XLS file is attached
