Fileziller restores the ftp account in the site manager. Due to the system failure, the system is reinstalled. In the past, fileziller configured many server link information lists. After fileziller was installed, even if the previous installation directory was copied, the site manager is still empty. The configuration information of these server links is very important. How can we restore them? When a fileziller system error was accidentally reported, the configuration information in the windows user directory was exposed. The path strength is as follows: C: \ Users \ your USERNAME \ AppData \ Roaming \ FileZilla can be found in this directory, all fileziller configuration files are in, copied out, overwrite the source configuration file in the directory corresponding to the new system. Start fileziller again, and all information is returned.
