Win32::File::SetAttributes() calls the Windows API function
SetFileAttributesA(), and that function is not capable of enacting
compression of the file or of setting the compression attributes flag.
This is documented at
http://msdn.microsoft.com/en-us/library/aa365535(VS.85).aspx and should
probably be documented in the Win32::File pod as well. (I think it's the
lack of documentation in the Win32::File pod that's the bug.)
The constant COMPRESSED, exported by Win32::File is really only of use with
Win32::File::GetAttributes().
The same applies to DIRECTORY.
Although SetAttributes returns true, I think you should find (by using
GetAttributes) that the 'compressed' attribute was *not*, in fact, set.
Seems odd that SetAttributes() returns true when trying (and failing) to set
COMPRESSED and DIRECTORY attributes .... it does so simply because that's
what FileSetAttributesA() returns.
Cheers,
Rob
