Compressed File Size - .NET Framework

Ron Clarke

Does anyone know how to get the compressed size of a file on disk?
FileInfo.Length gives the uncompressed size of a file, but I need to find
the amount of disk space taken up by files in compressed directories
(Windows XP). Getting the "compressed" attribute is available, but how does
one get the compressed size?

Thanks in advance.
