It may not sound like a YouTube video downloading app, but it is secretly one of the best.
This program is really a file hub. It’s a one-stop-shop for your media and other digital content. It’s also a service with a built-in web browser that lets you save the media by following these steps.
Step for save Media
1. Open the Documents Browser.
2. Go to the YouTube video you want to download.
3. Open the “Documents” section of the browser and select the “Save File” option.
5. Once the file is available it will be available through the Downloads section of the application.
From here, it is possible to move the file to the Photos section of the application.
The downside to doing so is that you can access the file with your camera roll instead of the app. This makes it easy to see and protects it from accidental occurrence.
If all of this sounds problematic, it is still a useful enough application to recommend documents by Readdel even if you use its stealth download features.
