Maybe you can provide a practical example of a case where you need to move files onto your system that can't be opened by any of the applications installed on your system. I never said the files couldn't be opened by any of the applications on my system -- I just said the files couldn't be managed by any of them. Note the very important difference. Regardless, here's an instance that came up just a few days ago: I have multiple computers and have software to deal with a certain file format installed only on some of them. I needed to back up the contents of a USB stick containing some such files on a computer that didn't have the software.
