Cant we access the txt file in the assets folder?

Question

Hi,

     I am developing a windows store app. I am storing a txt file in "Assets" folder. I am able to read the contents in it using 

var assetFolder = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFolderAsync("Assets")
            var file = await  assetFolder.GetFileAsync("<filename">);

But am not able to write anything into it. i.e., writeLinesAsync is throwing me "Access Denied exception". So don't we get a read/write access to such files in the installed location??

Thanks In Advance

Hello Rajesh,

You can't write file in apps installed location because, the app's installed directory is a read-only. For more information Show this document:

As a best practice you should copy file from your package to local or temp directory. Then you will have full access to it.

Hello Rajesh, 

For Copy file from installed folder to local folder than this code help to you:

async void CopyPrayerFile()
{
    //get the storage for your app 
    Windows.Storage.StorageFolder store = Windows.Storage.ApplicationData.Current.LocalFolder;
    StorageFile prayerFile = null;
    try
    {
        prayerFile = await store.GetFileAsync("Your file name");
    }
    catch (System.IO.FileNotFoundException)
    {}

    if (prayerFile == null)
    {
     

        StorageFolder install = Windows.ApplicationModel.Package.Current.InstalledLocation;
        StorageFile installFile = await install.GetFileAsync("your file name");

        installFile.CopyAsync(store);   
    }
}
