Importing quadtree based tileset into 26.2

lutzlr

I am trying to import a quadtree based tile set into global mapper and it does not seem to work. For testing I am just importing a level 3 dataset.

Base Data URL: file:///C:/testdata/level_03/%quad.jpg

Inside the level_03 directory I have 000.jpg 001.jpg.... up through 333.jpg

The tiles are all 256x256 and I have the max zoom level set to 3.

Is there something I am missing because every time I go to import it says "No working tiles could be found based on the provided base URL."
