Got it - thanks!
Follow-up, when I created the publisher, the snapshot was pointing to the network path I specified [\\SERVER\SNAPSHOT].
I see it created files and folder/subfolder as well.
\\SERVER\SNAPSHOT\unc\SERVER_TESTDB_TESTDB_PUBLISHER\20200122103014\(28524 items created)
I created the subscription and I got all the articles (all 6000+ tables) in the replicated server and replication was running as designed.
 Do I still need the files in the SNAPSHOT folder (all 28524 items)?
 If yes, when does this folder gets cleared out? I assumed that once the subscription reads the files and adds them into the replicated server, it deletes them.
