Merge two folders with mgm-files with more tiles per file

[franc]

Hello,

I have two folders with mgm-files of zoom 16 inside. Each mgm-file has 1024 tiles per file inside the folder. E.g. one folder is South Germany, one is North Germany.

I want to join now both, with the result that I have only one folder

\OpenCycleMap_16\

where both, south and north Germany are joined or merged.

Is this possible?

How?

If I just copy one over the other, most maps of one part are gone, this is clear.
I need a MapTileUNcacher I guess.

Please help.

Thank you,

Kindest Regards,
