Synchronize content of TGZ archives

[MWimmer]

It is not possible to synchronize the content of double packed archives, like TGZ. Synchronization within ZIP files works great, but within TARed and GZipped file all double file entries remain red.

A double click on a double-sided file already performs a single file comparison. Why could this not work for the whole archive?

This also don't working for contents of other archives. Synchronization supports only ZIP.

I think it will be good if at least equal files marked black after manual dblclk comparison but not left red.
