Hello,

Welcome to our Microsoft Q&A platform!

If you want to get all video file in your device, you can use Xamarin.Essentials: File Picker to achieve this.

The FilePicker class lets a user pick a single or multiple files from the device.

If you desire your user to pick multiple files you can call the FilePicker.PickMultipleAsync() method. It also takes in PickOptions as a parameter to specify additional information. The results are the same as PickAsync, but instead of a single FileResult an IEnumerable<FileResult> is returned that can be iterated over.

You can refer to the following code:

        var pickResult = await FilePicker.PickMultipleAsync(new PickOptions  
        {  
            FileTypes = FilePickerFileType.Videos,  
            PickerTitle = "Pick video(s)"  
        });  

        if (pickResult != null)  
        {  
            foreach (FileResult item in pickResult)  
            {  
                System.Diagnostics.Debug.WriteLine(" path =" + item.FullPath);  // here we can get the full path  
            }  
        }
