[galaxy-dev] number of dataset files within 000

Hi, The galaxy dataset files (file_path) are arranged within a subdirectory '000' (database/files/000). Will galaxy create a new subdirectory for storing datasets files after certain file count value is reached(say ~ 1000)? It may not be a problem while using web interface, but I am wondering if this could be a problem if user tries filesystem info commands from shell - e.g regular ls command output. Also, curious to know if subdirectory name '000' signifies something here? -- Thanks, Shantanu
