ファイルフォーマット一覧は、コンピュータなどの情報機器で使用されるファイルフォーマットと、その拡張子の一覧である。 ただし、各ファイルには拡張子は必ずしも必須ではなく、また拡張子は実際のファイルフォーマット（正確には各ファイルの内部のデータ形式）に必ずしも対応しているわけではないため、当一覧はあくまで参考である。 == 一覧 == *下表は「拡張子」順です。各項目（各列）順に表示するには、各項目名のソート記号をクリックしてください。 |class="sortable wikitable" !拡張子 !! 説明 !! 主な使用ソフトウェア !! 種類 |- ! ### |テンポラリーファイル |各プログラムに依存 |- ! #24 |プリンターデータ |LocoScript |- ! #IB |プリンターデータ |LocoScript |- ! #nn |ファイルイメージの一部 |Long |- ! #SC |プリンターデータ |LocoScript |- ! #ST |プリンター定義 |LocoScript |- ! $$$ |OS/2アーカイブファイル (例： archives.$$$, keys.$$$) |OS/2 |アーカイブ |- ! $$$ |テンポラリーファイル | |- ! $? |ZX Spectrumファイル | |- ! $00 |パイプファイル |DOS |- ! $DB |テンポラリーファイル |dBASE IV |- ! $ED |エディターのテンポラリーファイル |MS C |- ! $O1 |パイプファイル |DOS |- ! $VM |バーチャルマネージャのテンポラリーファイル |Windows 3.x |- ! )2( |LHAのテンポラリーファイル |LHA |- ! ??$ |バックアップファイル |P-CAD |- ! ??_ |Microsoftのパック化ファイル |Expand |アーカイブ |- ! ?DK |ディスクイメージ |Loaddskf.exe |アーカイブ |- ! ?UT |非パックのFTNメール |FTN software |- ! !ut |未完成のµTorrentダウンロード |µTorrent |- ! ___ |Adinfテーブル |Adinf |- !
