Firmware: One USB stick for 2 or more devices

 Hello community. If someone can help with this silly question.. but as updating firmware can turn into a nightmare, better to ask.

As different devices (CDJ,mixer, etc..) have an specific firmware named file, it should not be a problem to carry different files under the same USB stick root folder. Is that right?

Of course I mean that so I can carry only one stick for different devices' files and update the DJM or the CDJ if I need to.

Cheers.
