Adding more than 8 folders.

MinimServer keeps all the internal data structures needed for browsing the library in memory. These limits enable a more effcient memory representation for the in-memory structures, which is important when running on low-end devices with limited amounts of memory available. The limits are compiled into the MinimServer code and can't be increased at runtime.

Have you seen a MinimServer message about the 65000 limit being exceeded? I am asking this because MinimServer doesn't count any folders that don't contain music files, so you might be OK even if there are more than 65000 subfolders on disk.
