Hey everyone!
mcandial’s suggestions for Read/Write files is the best solution to this.
I am running Ubuntu 20.04.1 LTS Focca Fossa with a 3.36.3 GNOME version. WPS can’t access the file because the SNAP implementation with the application sets the Read/Write functionality to OFF when extracting content from external HDD’s.
You can see this specification with the file attached.
