cmMaintCmdDirectory is a read-write display string specifying the directory on the primary and secondary file servers where a maintenance command's uploaded files will be stored, though the description notes it is ignored for bulkCPEDownload. An administrator sets this to organize backup or statistics files into a predictable folder structure on the file server. For example, an operator might set cmMaintCmdDirectory to '/backups/chassis14' so that chassis's configBackup uploads land in a clearly identified location.
