Hi Maurus, no magic here 😃. We use a standard html5 input field of type="file" with the attribute "multiple". When using an angular app it could look like this, for example: <input type="file" accept=".snap, .app" multiple /> In our case the input field is hidden and controlled using javascript. <input #inputFile type="file" accept=".snap, .app" multiple (change)="add.emit($event.target.files); $event.target.value = null" style="display:none;" /> Best Jochen
