Hi Feris,
may be this is a more or less hacking approach, but I have tested
the valid format with a magic number comparison.
When I read a file that should be a MS Office document it should
have at least the filesystem structure that all MS documents have
(old once for shure).
So I compare the this pattern from the file beginning
/**
* Header des MS Compound Document Format á la magic number test
Documentation u.a. in
* http://sc.openoffice.org/compdocfileformat.pdf
*/
private static final String COMPOUND_DOC_HEADER_START =
"d0cf11e0a1b11ae100";
If this is in hex comparison the start I'll treat it as an office file.
