how to get file from temp foldre using StorageFile.GetFileFromPathAsync()

Question

Hi,

I am trying to download a .pdf in the temp folder.

Here is the code

 var uri = new Uri("http://www.nakcollection.com/uploads/7/7/7/4/7774039/the_man_in_the_red_underpants_book.pdf");
            StorageFolder folder = ApplicationData.Current.TemporaryFolder;
            StorageFile file = await folder.CreateFileAsync("one.pdf");
            BackgroundDownloader download = new BackgroundDownloader();
            DownloadOperation downloader = download.CreateDownload(uri, file);
            StorageFile file1 = await StorageFile.GetFileFromPathAsync("");

Now I want to use that file how can I get that file using

StorageFile.GetFileFromPathAsync("");

Hi Sameel Nawaz,

Please try to use the following code to see if it works:

StorageFile file1 = await StorageFile.GetFileFromPathAsync(file.Path);

Besides, I will recommend you use the StorageFile.GetFileFromApplicationUriAsync to get the StorageFile.

var uri = new Uri("ms-appdata:///temp/one.pdf");
StorageFile file1 = await Windows.Storage.StorageFile.GetFileFromApplicationUriAsync(uri);

Thanks, a lot it worked :)

Here is the revised version of the code. It might help others too. :)

var uri = new Uri("http://www.nakcollection.com/uploads/7/7/7/4/7774039/the_man_in_the_red_underpants_book.pdf");
            StorageFolder folder = ApplicationData.Current.TemporaryFolder;
            StorageFile file = await folder.CreateFileAsync("one.pdf",CreationCollisionOption.ReplaceExisting);
            if(file !=null)
            {
                //Download form uri to file
                BackgroundDownloader download = new BackgroundDownloader();
                DownloadOperation downloader = download.CreateDownload(uri, file);

                //set download priority
                downloader.Priority = BackgroundTransferPriority.High;

                //request uncontrained download
                UnconstrainedTransferRequestResult result = await
                    BackgroundDownloader.RequestUnconstrainedDownloadsAsync(new DownloadOperation[] { downloader });
                
                // start downloading
                await downloader.StartAsync();
                //the download is now finished
                var tempUri = new Uri("ms-appdata:///temp/one.pdf");
                StorageFile file1 = await StorageFile.GetFileFromApplicationUriAsync(tempUri);
                if (file1 != null)
                {
//user defined function for further usage of file
                    LoadFile(file1);
                }
            }
