noun which may take the genitive case particle 'no'
self-executing
Computing term for a file or program that runs automatically when opened or triggered, without manual execution.
この自動発効ファイルを開くと、インストールが始まります。
When you open this self-executing file, the installation will start.
実行ファイル is a general executable file, while 自動発効 specifically means self-executing, often implying automatic launch without user action.
Compound of 自動 (automatic) and 発効 (coming into effect, execution). The exact origin is uncertain; likely a technical coinage in computing contexts.
