What do the numbers on the scenery files and folders mean, anyway?
Scenery files and folders are organized into a grid by latitude and longitude. Each scenery file covers one square degree of the earth and is named according to its coordinates. For example, the file +42-089.ENV covers the square degree that has 42 degrees North and 89 degrees West as its south-west corner. Each folder contains all the scenery files for a 10 degree square. So +42-089.ENV would be contained in the +40-090 folder. All scenery folders are contained in the Resources\Earth Nav Data folder. Note: In version 5.xx, there is an additional leading zero on the latitude. The preceding ENV would be named +042-098.ENV in 5.xx, and its folder wold be named +040-090.
