Generally, Foxmail saves a user's message to the mail directory of its installation directory by default. If the user needs to save the message to a specific directory, such as installing Foxmail to C, and saving the contents of the message to a D disk that specifically holds the data.
Users want to save messages from an account to a different directory before using Foxmail. Just click the Select button under Mailbox path in the Create New User account dialog box that pops up when you create a new account, open the Browse for Folder dialog box, and then select the folder you want.
If the user has set up a corresponding mail account, and now want to keep all previous user settings and messages based on the adjustment of the message to save the directory, you should first copy the account mailbox directory to be moved to the target directory, and remove the Account.stg file from the copied directory, then delete the corresponding account in Foxmail, then create a new account that is the same as the one you just deleted, and assign the mailbox path to the path of the copied mailbox, and then copy the removed Account.stg file back.
