ZDMC V21.0 is working fine on my Z9X 8K device and I am able to read, write and delete files and folders on attached USB HDD and memory stick devices. However when I run the Kodi Backup add-on V1.7.3 and attempt to define an output folder for the backup file it consistently declares an error with the message "Make sure the selected folder is writable and that the new folder name is valid". I have tried several devices and folder names to no avail. What am I doing wrong?
