IV 説明書

IV (Image Viewer) は、シンプル・軽量をコンセプトに開発中の画像ビューアです。

ZIP ファイルのフッタを読まずに先頭から順にデコードすることにより、多重圧縮 ZIP を高速に処理します。

Windows XP / 7 / 8.1 / 10 (x86, x64) + SSE2 または Windows 10 on ARM

IV 自体はインストールに特別な作業は必要ありません。IV フォルダごと任意の場所に置くだけです。

関連付けを行うには IV.wsf を実行して IV を既定のプログラムに登録する必要があります。再度実行することで解除できます。

RAR 形式の書庫を開くには、別途 unrar.dll (32bit版用) または unrar64.dll (64bit版用) が必要です。 » UnRAR.dll ダウンロードページ (ARM 版は非対応)

アンインストールの際は、関連付けの解除を行ってから、インストール時にコピーしたファイル、および設定ファイルが置かれる %AppData%\IV フォルダを削除してください。
