My Passport won't back up every file

I bought a new My Passport and have been enjoying it so far! I do have an issue where not every file is being backed up on it correctly. some of them have long file names, which makes sense, but others don’t. they do have names like cache.dat and notiylimit.lock, so I’m not sure if that has anything to do with it.

I’ve heard other recommend using Smartware, but it looks like that software can’t be used on My Passport. What can I do?
