Samba mangles a long filename into an 8.3 filename, for example:
-rw-r–r– 1 42781900 42781900 1432 Oct 16 21:00 2ZAOMT~P.XML
-rw-r–r– 1 42781900 42781900 1432 Sep 14 09:00 2ZCLAI~F.XML
-rw-r–r– 1 42781900 42781900 1432 Dec 3 21:00 2ZDTUD~9.XML
-rw-r–r– 1 42781900 42781900 66047 Sep 24 21:00 2ZG7PO~5.XML
Add “mangled names=no” to the [global] section in /etc/samba/smb.conf and then restart the smb service.
root# cat /etc/samba/smb.conf
–cut
[global]
unix charset = UTF-8
mangled names=no
–cut
root# systemctl restart smb
And now, everything is okay 😉
