I believe if the file exists it will be overridden,

and if you want to separate the namespace for each user, so the redundant file name wont collide whit each others:

like user 1 uploads an untitled.jpg & user 2 uploads an untitle.jpg

in this case you can use the instanceId with id of the users (or any string to use as a namespace)

$resumable = new Resumable($request, $response, $instanceId);
