Abstract: A terminal device capable of managing a storage capacity is provided. The terminal device includes a storage which stores a plurality of contents, a controller which selects candidates to be deleted according to a characteristic value from among the plurality of contents and generates a deletion candidate list, a display which displays the deletion candidate list, and an input which receives a user command to select content to be deleted from the deletion candidate list. A method of managing a storage capacity includes checking a storage capacity of a terminal device; in response to the storage capacity meeting a preset capacity condition, selecting candidates to be deleted from among a plurality of contents and generating a deletion candidate list; displaying the deletion candidate list; and deleting at least one content selected from the deletion candidate list.
