1. First, create a new account, and put all the used mailboxes into the new account (after this step, the space on the hard disk actually increased, although the old account did not have a mailbox, and the hard disk space was not actually released). Back up the account.stg file in the original account (this file is some settings in the original account, such as "other POP3 information"), and then delete the old account (you can use the option of deleting the account in FOXMAIL or manually delete it in the hard disk, and I think the second method works best). After these operations, change the new account name to the original account name. Copy the backup account.stg back to the directory of the new account.

2. First, create a new account, move all the scrapped parts in the old account to the "scrap box", and then directly copy the trash.ind and trash.box in the new account directory to the old account, overwriting the original two files. Delete the newly created account when finished.
