Paths Paths
----- -----
* `RUN_IN_PLACE=1` (Windows release, local build) Minetest keeps and looks for files mostly in two paths. `path_share` or `path_user`.
* `$path_user`: `<build directory>`
* `$path_share`: `<build directory>`
* `RUN_IN_PLACE=0`: (Linux release)
* `$path_share`:
* Linux: `/usr/share/minetest`
* Windows: `<install directory>/minetest-0.4.x`
* `$path_user`:
* Linux: `$HOME/.minetest`
* Windows: `C:/users/<user>/AppData/minetest` (maybe)
`path_share` contains possibly read-only content for the engine (incl. games and mods).
`path_user` contains mods or games installed by the user but also the users
worlds or settings.
With a local build (`RUN_IN_PLACE=1`) `path_share` and `path_user` both point to
the build directory. For system-wide builds on Linux the share path is usually at
`/usr/share/minetest` while the user path resides in `.minetest` in the home directory.
Paths on other operating systems will differ.
