[Transferring Ownership]

I re-installed my OS.   I was the owner.  I can't seem to figure out how to re-instate ownership of a folder or transfer ownership.   All other peers were just read/write

[Clean OS Install. How to restore account settings?]

Similar situation.  Needed to wipe and re-start on a mac that was to "owner" of several folders.  Before wiping I disconnected all the folders.  I may have unintentionally named my machine a slightly different name which would change the folder paths.  I am a little concerned about relinking the folders since they aren't showing in my resilio app after re-install and applying my license.  Is there a way to be sure this computer retains "owner" status on the folders once I reconnect the folder?
