The present invention relates, for example, to a recording apparatus and method suitable for use in temporarily storing data recorded to a detachable recording medium. In step S501, a directory, recorded to an MS, to be stored is searched, and its capacity is calculated and displayed on a display screen. In step S502, a user operation is accepted to select the directory to be stored. In step S503, all files that belong to the selected directory to be stored are retrieved, and recorded to an HDD as one archive file. In step S504, the original object directory and a file name of the archive file are stored in a matching relationship with each other into the recorded archive file. In step S505, the directory which has been stored in the HDD is deleted from the MS. The present invention is suitably applied, for example, to an audio data server.
