Problems with paths longer than 259 characters

[rikyoz]

I use 7zip Dll v19.00, Bit7z v3.1.1 and Windows 10 x64 v1909
I have tested with "Windows 10 long path name" enabled and disabled: same result.

This is really weird. Have you tried to prepend \\?\ to the path passed to BitCompressor::compressDirectory, e.g., L"\\?\C:\\Cartella condivisa"?

If I prepend "\\?\" it works properly.
If this behavior is normal, I think, if I don't prepend "\\? \" and there is a paths longer than 259 characters, bit7z should throw an exception or alternatively add note in the documentation to check the length externally to bit7z.

Thanks, Fabrizio.

Added the option BIT7Z_AUTO_PREFIX_LONG_PATHS for automatically prepend \\?\ to paths in v4.0.0.
