I have added a new external sandisk to my macbook.  This drive is formatted with exfat.  Commander One does not show this drive.  The drive does show in finder and I am able to move/copy files with finder to the ssd.  Is Commander One not compatible with exfat drives?  What needs to be done for Commander One to recognize this drive?

I also have another external hard drive that is formatted with Mac OS Extended.  This drive does not show in Commander One either.

I have searched to find if these drive formats are not compatible with Commander One but haven't found any information on that topic.
