Also, when areas overlap do duplicate tiles get stored on disk? IE waste SDCard space.

The same map you will need less space when using sqlite. Each file requires additional space not actually used. Thousands of files will be thousands of small spaces sd wasted.

Moving a file, even large, is fast. Moving thousands of files is always slow.

Yes I understand that. But the operation of copying the map files to an SD card is a once only action (if you have a large enoubgh card). Formatting the SD with a small cluster size helps reduce the SD waste per file.

I was thinking are there benefits and disadvatages of using each file format within Orux?
If areas overlap, I guess tiles are duplicated in SQLite.

Hi;

no real benefits/disadvantages. It is not possible to use maps with more than one layer per zoom level with both formats.

I have added a patch to MOBAC to avoid this kind of maps.
