dim td as FsResultUStr = CreateTempDir( "fbdoc" )
dim as ustring dir_ = td.Value( )

CreateDirAll( PathJoin( dir_, "src", "inner" ) )
WriteAllText( PathJoin( dir_, "src", "f.txt" ), "x" )

'' Recursive, and it returns the NUMBER OF OBJECTS COPIED
dim r as FsResultI64 = CopyDir( PathJoin( dir_, "src" ), PathJoin( dir_, "dst" ) )
print r.IsOk( )              '' true
print r.Value( ) >= 2        '' -1 (true) -- the file and the inner directory

print IsFile( PathJoin( dir_, "dst", "f.txt" ) )         '' true
