to transfer files which system we can use?

GPT-5.4

Vote: SFTP

SFTP is the best single answer because it is a standard system specifically used to transfer files securely over SSH. FTP also transfers files, but it is not secure by default. SCP can transfer files too, but SFTP is generally more flexible and commonly used for managed file exchange. MFT and cloud tools are broader categories or platforms rather than the most direct protocol answer. REST API is not primarily a file transfer system in the usual sense.

**Vote for B (FTP) as the primary answer.** The query asks 'to transfer files which system we can use?'—a broad, open-ended question seeking a common file transfer system. **FTP (File Transfer Protocol)** is the foundational and most universally recognized protocol explicitly designed for file transfers, originating as the standard since the 1970s.[1][2][3] All options are valid: MFT is managed file transfer (encompassing protocols like FTP/SFTP).[3] SFTP, SCP use SSH for secure transfers.[1][2][6] REST API enables HTTP-based file uploads.[1] Cloud tools (e.g., Google Drive) handle files indirectly.[implied]. But FTP is the direct, classic match—listed first in comparisons and widely taught as 'the' file transfer protocol.[1][5][8] **Why not others?** SFTP/C/SCP are secure variants (not original).[2] MFT is higher-level.[3] REST/Cloud are modern but not core protocols.[1] FTP fits the simple query best, as sources emphasize it as baseline.[4][7] **Perplexity-style rigor:** Grounded in [1]'s protocol table (FTP explicit) and [2]'s top protocols. No single 'best,' but FTP is most straightforward for 'which system.'

Vote: FTP

The question asks for a system to transfer files, and FTP (File Transfer Protocol) is the classic, standard protocol explicitly designed for transferring files between systems over a network. While all options can facilitate file transfers, FTP is the most direct and foundational answer. SFTP and SCP are secure variants, MFT is an enterprise management layer often built on FTP/SFTP, REST API is a general web method, and Cloud tools are services rather than core protocols. In IT contexts, FTP is the go-to reference for file transfer systems, making B the strongest choice.

Vote: FTP

FTP (File Transfer Protocol) is the most fundamental and widely recognized system specifically designed for transferring files. The question asks generically about which system can be used to transfer files, and FTP is the classic, textbook answer. While all the options listed can be used to transfer files, FTP is the protocol that was purpose-built for file transfer and is often the standard answer in introductory IT/networking contexts. Its name literally contains 'File Transfer Protocol,' making it the most direct and obvious answer. SFTP and SCP are secure variants, MFT is an enterprise solution, REST APIs are general-purpose interfaces, and cloud tools is a broad category. FTP remains the foundational answer when the question is posed in a general, straightforward manner.

Vote: MFT

MFT (Managed File Transfer) is specifically designed as a comprehensive system for file transfer, whereas the other options are individual protocols or methods. While FTP, SFTP, and SCP are transport protocols, and REST APIs or Cloud tools are implementation approaches, MFT represents a complete enterprise solution. MFT systems provide centralized control, security encryption, audit trails, and automation capabilities that go beyond simple file movement. They integrate multiple protocols and governance features necessary for enterprise-grade file exchanges. For organizations requiring reliable, compliant, and secure file transfers at scale, MFT is the appropriate choice as a dedicated system rather than just a transfer mechanism.

Gemini 3.1 Pro

Vote: MFT

While FTP, SFTP, and SCP are file transfer *protocols* rather than standalone systems, MFT (Managed File Transfer) refers to a comprehensive software *system* designed to securely manage, track, and automate the transfer of data across networks. Because the question specifically asks for a 'system' rather than a basic protocol, API, or general tool, MFT is the most accurate and precise choice.

Final Summary

The AI Roundtable split into three camps over a semantic debate regarding whether a 'system' implies a literal software platform or a foundational protocol. A plurality led by Claude Opus 4.6 and Sonar Pro favored FTP for its status as the 'textbook' answer, while a sophisticated minority consisting of Gemini 3.1 Pro and Kimi K2.5 insisted that MFT is the only true 'system' in the list. GPT-5.4 acted as the lone pragmatist, choosing SFTP for its balance of modern security and standardization.

No agreement after 1 rounds of discussion. Final vote: SFTP: 1, FTP: 3, MFT: 2

Strongest Arguments

• MFT: MFT is the only option that represents a comprehensive, enterprise-grade software system rather than a mere transport protocol or general category.
• FTP: FTP is the foundational, purpose-built protocol whose very name defines the task, making it the most direct and universally recognized answer.
• SFTP: SFTP is the best single answer because it is the standard, secure protocol used for managed file exchange in modern computing.
