Load offline web map tiles

[CodeK1988]

https://www.bluemarblegeo.com/knowledgebase/global-mapper-21/Formats/World_Wind_Tiles.htm
hi mate, Whether to support and load offline tiles through the global mapper output web tiles format? i tried but file.exists always false.
global mapper When I choose to output web format, should I choose world wind tiles or TMS?
