GUI GNOME File Manager and PCManFM don't see my backup files - Ubunto 20.04

As one of my important stapes into the Linux world is - Backup, I finnaly managed to setup rsync / crontab to do the job.

This was with intensive help from several forum members here, I am thanking them again.

The problem however is that - I can see the backup files through a Terminal command, but in eiker of the above file managers, the backup folders in the external "Target" SD device show as empty.

Code:alex@alex-nuc8i7hnk:~$ ls -l /media/New-SD-512/sun/alexfolders
