The subdirectories `mods`, `modpacks`, and `worlds` will also be checked accordingly. To change the source location of downloaded files, set `CF_DOWNLOADS_REPO` to an existing container path. To disable this feature, set `CF_DOWNLOADS_REPO` to an empty string.

Ideally mod developers should [use correct registrations for one-sided client mods](https://docs.minecraftforge.net/en/latest/concepts/sides/#writing-one-sided-mods). Understandably, those code changes may be non-trivial, so mod authors can also add "Client" to the game versions when publishing.
