owned by the deleted account’s user ID (UID). If you create a new account and specifically

1. Remove the user from the user accounts list;

2. Remove the user’s home directory and all its contents.
Files not contained in the user’s home directory, but owned by that user will remain on the
system. The file will still be owned by the deleted account’s user ID (UID). If you create a new
account and specifically assign it the UID of a deleted account, it will then become the owner of
any such ‘’orphaned’’ files.

Selecting Leave the account’s data in place on the Deleting account <accountname>:
1. Remove the user from the user accounts list;
2. Leave the user’s home directory (with all its files) in place.

If you create a new account and specifically assign it the UID of a deleted account, it will then
become the owner of these ‘’orphaned’’ files.
