You definitely should report with one error object, and you won't find function in Node.js API that returns more than one error.
Most straightforward way would be to fail your function as soon as first error occurs, and report with that error. However if you'd like to have more complete solution, that tries to delete all files and collects error information on the way, then you may want to report all approached errors on one error object. You can do it either via error.message or via other custom property on error object.
