You can have a unique file name automatically generated for you without any custom methods. Just use the following with the StorageFolder Class or the StorageFile Class. The key here is: CreationCollisionOption.GenerateUniqueName and NameCollisionOption.GenerateUniqueName

To create a new file with a unique filename:

var myFile = await ApplicationData.Current.LocalFolder.CreateFileAsync("myfile.txt", NameCollisionOption.GenerateUniqueName);

To copy a file to a location with a unique filename:

var myFile2 = await myFile1.CopyAsync(ApplicationData.Current.LocalFolder, myFile1.Name, NameCollisionOption.GenerateUniqueName);

To move a file with a unique filename in the destination location:

await myFile.MoveAsync(ApplicationData.Current.LocalFolder, myFile.Name, NameCollisionOption.GenerateUniqueName);

To rename a file with a unique filename in the destination location:

await myFile.RenameAsync(myFile.Name, NameCollisionOption.GenerateUniqueName);
