Temporary Video Files Problem

Question

I am developing a Flashlight app for Windows Phone. First the problem was that it was not working on some higher end phones which I solved by adding the following code to my solution:
 // Create video encoding profile as MP4 
                    var videoEncodingProperties = MediaEncodingProfile.CreateMp4(VideoEncodingQuality.Vga);
                    // Start Video Recording
                    var videoStorageFile = await KnownFolders.VideosLibrary
                        .CreateFileAsync("tempVideo.mp4", CreationCollisionOption.GenerateUniqueName);
                    await _mediaDev.StartRecordToStorageFileAsync(videoEncodingProperties, videoStorageFile);
Now the problem is that the above code create a temporary video file everytime Torch is enabled. Is there anyway to delete those files created when the torch is disabled by user?

Hi Prajjwal,
>>Now the problem is that the above code create a temporary video file everytime Torch is enabled. Is there anyway to delete those files created when the torch is disabled by user?
We can use StorageFile.DeleteAsync method to delete this temporary file:
https://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.storagefile.deleteasync.aspx
StorageFile videoStorageFile;
private async void FunStart()
// Create video encoding profile as MP4
var videoEncodingProperties = MediaEncodingProfile.CreateMp4(VideoEncodingQuality.Vga);
// Start Video Recording
videoStorageFile = await KnownFolders.VideosLibrary
.CreateFileAsync("tempVideo.mp4", CreationCollisionOption.GenerateUniqueName);
await _mediaDev.StartRecordToStorageFileAsync(videoEncodingProperties, videoStorageFile);
private async void FunStop()
//Something to stop torch....
await videoStorageFile.DeleteAsync();
