-----------------------------------
This is what I know,
The v3 file's first 30 bytes includes "HWP Document File V3.00 \x1a\1\2\3\4\"
for recognizing v3 file.
And the v5 file stores "HWP Document File" in the first 32 bytes of file header.
I wonder, whether "HWP Document File" can be unique bytes of v5 file or not.
> Detection is not working properly for detecting HWP 5.0 file
