Configuration / filesystem.directories
This config option enables you to override global config options on directories matching a specific pattern. This pattern can either be a public file system path like "/files/documents" or a directory name like "images".
If a public file system path is specified that specific path and all directories below it would get the new option. If you specify only a directory name any directory anywhere matching that exact name would have the speicifed config options.
