creating new user

Hi,

I have an early MacBook pro on Catalina. I've had a single user, but became convinced that the user file was corrupted (it ostensibly was twice the size of the individual files, other files seemed to have disappeared (I do have outside backup, but on highsierra)). - Anyway, my solution was to create another user, then shift the files etc. from the old to the new, and then trash the old (corrupt) file. However, between varied permissions on different files, bookmarks for Safari, and Mail Accounts, I'm finding this pretty hard to do, and in fact so far have not succeeded. - Is there a relatively straight forward way to go about this? thanks for any help - Ray
