I am using LibreOffice on Linux. One way I know of viewing and removing metadata from a LibreOffice file is going to
File -> Properties -> General, unchecking “apply user data” and click reset. Then go to “Description” and “Custom” Properties and remove information from there, if exists.
Does it truly remove all the metadata or something is left and what is it and what other methods can I use to remove it?
Also, if I unzip a LibreOffice file, is
contents.xml the only place where metadata may be found?
If I forgot to remove any metadata, is it possible that the username is transmitted?
