I have late 2013 iMac with Catalina. I have 7 hard drive attached to it. I also have an iPhone. Some of the hard drives I want to share to access the hard drives and files on them. I have shared the drives through file sharping processed however when views through files on iPhone nothing shows ups. My intent is to move file from my phone to with out touching my computer and like my recipe drive read off the recipes on my phone add them to it form my phone. Another not I got it where iPhone will see them all but when I get to the hard drive it says nothing can be displayed. However my local computer hdd only has the shared folder as accessible.
