| Some servers support more than one of these protocols. This document contains a comparison to help you to decide which is most appropriate for your needs. The comparison describes both features that are characteristic to the specific protocol as-is, and features that are caused by the implementation of the protocol in WinSCP. | Some servers support more than one of these protocols.

| ^ Directory operations | Recursive operations with directories (deletion, permissions change) must be performed separately for each file. Thus operations can take a long time, especially for directories with a large number of files. ||| Recursive operations with directories (deletion, permissions change), can be done with a single command (''rm'', ''chmod'', etc). Thus they are quick. On the other hand it limits some functionality. | | ^ Directory operations | Recursive operations with directories (deletion, permissions change) must be performed separately for each file.

| ^ Timezone and DST issues with [[timestamp|file time-stamps]] | Theoretically no issues, as the protocol requires timestamps to be in UTC. Practically some of the SFTP servers have problems with DST. | Theoretically no issues, when the server supports ''MLSD'' command, as the comment requires timestamps to be in UTC. Practically some of the FTP servers have problems with DST. When the server supports ''LIST'' command only, behavior is undefined and timezone offset may need to be configured. | Theoretically no issues. | Some shell commands are influenced by daylight-saving time. For example, the ''ls'' command can return a different time than ''scp''. Thus, after transfer, the time-stamp of the file can be different. Also there can be an additional difference caused by the server timezone offset. This causes trouble when comparing directories and [[task_synchronize|synchronization]]. | | ^ Timezone and DST issues with [[timestamp|file time-stamps]] | Theoretically no issues, as the protocol requires timestamps to be in UTC.
