If you know where you mounted the directory/archive, you should be able to 
reconstruct the full path. (Maybe there is also a function to give you the 
mountpoint of an archive, I do not know that off hand.)

virtual_filename;
archive_filename = getRealDir(...);
archive_mountpoint = figure_out_mountpoint(archive_filename);
relative_filename = subst(archive_mountpoint, "", virtual_filename);
full_filename = archive_filename + relative_filename;

But generally I assume it is discouraged to care about the real filename, 
since this complicates the whole stuff, also in places where you might not yet 
think about.
