Creating tar archive with RootPath property set

[MarcoGit82]

Hello everybody.

I don't know if this is a bug or not.
I'm trying to create a tar archive starting from a folder, let's call it c:\temp\template.
I also want to avoid to have in my tar the entire path, so I'm setting the RootPath of my TarArchive instance to c:\temp\template as well, because I want my tar file to contain only the subdirs of c:\temp\template.
I get what I want but also a folder with no name.

I run in debug and actually that folder with no name is added as entry,
because the RootPath value is subtracted to the source directory.
But is that wanted?
How can I avoid this?

Thanks,
Marco
