Using SevenZipCompressor (named c) from 0.64 and .Net 4.0 in 64 bits windows 8.1.
c.CompressionMode = SevenZip.Create;
c.PreserveDirectoryRoot = true;
c.DirectoryStructure = true;
c.CompressionMode = SevenZip.Append;
Directories (in the archive) are created representing the 2 calls to CompressDirectory(),
however, the call to CompressFiles() adds the files at the archives "top level", i.e. structure is lost.
How to do correctly ?
(Actually what I want to do is to CompressDirectory() but only partly and not by search pattern, but by an array of filenames or something similar).
