📦 Installation & Usage

1. Go to the Latest Release.
2. Download the .zip file (e.g., FFmpeg.Video.Audio.Downloader.v1.2.1.zip).
3. Extract the contents to a folder of your choice.
4. Pro Tip: Right-click the .exe file, select Properties, check the Unblock box at the bottom, and click OK. This prevents Windows from asking for permission every time you run the app.
5. Run the .exe file, select your desired video/audio format, paste a link, and start downloading!

Important

Note on Windows SmartScreen: Because this is a new, independent application, Windows may show a warning. If you haven't "unblocked" the file as described above, click "More info" and then "Run anyway".
