Pretty good.
So far I like the application. I’m using it mostly to view files on a shared drive. Commander One is inconvenient because you need to allow it access to whichever drive you intend to view documents in, so you can’t use it for local and network drives.
I’m also having issues figuring out how to change the preview thumbnails.
So, it’s pretty good. Not great.
