How To Get Removable Devices? Before using this code, You need to enable (check) Removable Storage in Capabilities (in Package.appxmanifest). Warning : Due to async and await keywords, The debugger might not receive some values at breakpoints.  StorageFolder Instance = KnownFolders.RemovableDevices; This how you can get Removable Devices. How To Get List Of Removable Devices? StorageFolder Instance = KnownFolders.RemovableDevices; IReadOnlyList<StorageFolder> Devices = await Instance.GetFoldersAsync(); How To Get Removable Devices By Array Index?

StorageFolder Instance = KnownFolders.RemovableDevices; IReadOnlyList<StorageFolder> Devices = await Instance.GetFoldersAsync(); StorageFolder Device = Devices[0]; How To Get All Directories And All Files From Current Pat...

I will create number validation in TextBox. This algorithm only allow numbers while user press any key. TB.PreviewTextInput += (sender, e) => { if (e.Text != "0" && e.Text != "1" && e.Text != "2" && e.Text != "3" && e.Text != "4" && e.Text != "5" && e.Text != "6" && e.Text != "7" && e.Text != "8" && e.Text != "9") { e.Handled = true; } }; Here is little demo on PreviewTextInput. I am researching on validations for TextBox. In future, I will create more detail about it.
