PDF cannot open in Adobe DC but, can in Chrome and Edge.

I have a windows 10 Computer (Drive format NTFS) with the free version of Adobe Reader installed.  I have a USB Flash Drive (Drive format FAT) When I try to open the PDF on the flash drive I get the error. 

Adobe Reader could not open … because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn’t correctly decoded)."

If I open the PDF on the USB drive using Chrome or Edge the file opens.  Oddly I gave the USB flash drive to two friends and they could open the USB PDF file.  If I copy the PDF to the local C: Drive of my computer from the USB Flash drive I can open the PDF. 

It is not clear why I can't open the file from the USB drive using my verions of Adobe DC (Reader/Free)? I uninstalled Adobe and reinstalled to make sure I have the current version.
