MikroTik RouterOS implements a File Transfer Protocol (FTP) server feature

Description

MikroTik RouterOS has an industry standard FTP server facility. It uses ports 20 and 21 for communication with other hosts on the network. Uploaded files as well as exported configuration or backup files can be accessed under /file menu. There you can delete unnecessary files from the router.

Authorization for FTP service uses router's system user account names and passwords. The ftp local user policy controls the access rights to the FTP server.
