$ stat /usr/bin/file | grep Device

$ stat ~/.bashrc | grep Device

Apply small patch from http://www.davidfaure.fr/2020/uds_device_test.diff,
then:
$ kioclient5 openProperties /usr/bin/file
"DEVICE" 804
$ kioclient5 openProperties ~/.bashrc
"DEVICE" 803
without this change DEVICE would be "8" for both of these files.
