Verify copy of raw files in iPhone App

I have a My Passport Wireless that I’m trying to incorporate into a travel photography workflow. I would like to be able to download raw images off an SD card for backup.

I understand that the My Cloud iOS app doesn’t know how to read the raw file, and that’s okay with me. But I have a problem that it is not showing me the files at all — it’s as if they are not there. When I upload a card with raw files to the drive, the iPhone app only shows me the first file uploaded. If I look at the folder on my desktop computer, I can see all the files, but on the phone only the first.

This is really a problem because I only travel with the iOS device and therefor can’t verify that the images have successfuly copied to the drive.

Has anyone else bumped into this? 

Maybe the problem lies with the iPhone and not the MPW, since the iPhone doesn’t know what to do with a RAW file, it ignores its existence (as it would for any other file extension it does not recognize).

There is an Android app called ES File Explorer that allows one to see any file on the device, but since Apple (in their ultimate parental wisdom) doesn’t allow an app like ESFE on their devices, we just may be SOL here (unless someone can tell us about a ESFE wannabe for the iOS devices).  There is a nice iOS app I use called FileBrowser, that appears to show me most any file, so maybe that would work for showing RAW files.

Very strange, all my raw files shows in the My Cloud app as a list of files.

What iPhone and version of iOS and version of My Cloud app do ypu have?
