Does the reload system need to reinstall the Foxmail?

No need. As long as you keep all the files of Foxmail, the system can use the original foxmail after reloading.

Keep foxmail files, you need to keep all the files and folders in the Foxmail directory, and the mailbox directories for each account. The mailbox directory for an account defaults to the next subdirectory with the same name as the account name, and the mailbox directory is the specified folder if the mailbox path is specified when a new account is created, by default, the Foxmail mail directory. The reload system is especially good at keeping the mailbox directory.

You can set up shortcut icons for startup Foxmail on the Start menu, program, Desktop, and shortcut bars by using the Foxmail tool menu.

In addition, multiple operating systems installed on the same computer can use the same foxmail on the hard drive.
