Each of the journal files are kept in their own directly. That directory
is the machine id of the given machine (as specified by /etc/machine-id
file).

So rather than "all in one folder" you should keep them all in their
separate machine-id-based sub-directories. You can then use journalctl
-m to automatically merged all the logs from all the machines into out
stream of log output.
