Yes, SFTP (Secure File Transfer Protocol) supports large file transfer. SFTP is designed to handle large files, and its architecture allows for efficient and secure transfer of files of any size. SFTP uses a unique, encrypted connection between the client and server, providing end-to-end security during file transfer. It also allows for resuming partially transmitted files, ensuring that large file transfers can be resumed from where they were interrupted in case of network failure or other issues. Overall, SFTP is a reliable, secure, and efficient method for transferring large files.
