operating level of file manager CAJA

[wpshooter]

Are there any instances or circumstances in which file system operations like copying files from one place to another, or similar operations
could be performed by/within the file manager (CAJA) as administrator with SU rights and thus the ownership of the files would
be switched from ownership of the normal Linux user account to ownership by the administrator account, say for instance if you
had just done something at the terminal as SU and then went directly to the file manager and the administrative rights were still
elevated, could this potentially change ownership of files, in other words, those files would become protected like Linux system files as
if ownership was changed via the terminal - can file ownership be changed via any GUI application ?

Thanks.

Yes.

can file ownership be changed via any GUI application ?

If "any" mean all GUI apps? Then no.
If "any" mean there is at least one program with a GUI that can change file ownership, then yes.

Am I correct that CAJA is not, that's the only one I am concerned with ?

Thanks.

Of course it can do that, like probably any file manager. Right click > Properties > Permissions > Owner. That's assuming you are running Caja as superuser, because a regular user is of course not authorized to change file ownership.
