| - | ^ Speed | Transfers are faster in general. Protocol do not use packet confirmation, yet it causes some serious problems. | Transfers are slower in general due to necessity to wait for packet confirmations. In versions 3.7.2 and 3.4 several optimalisations were introduced that almost reduced the disadvantage over SCP. | | + | ^ Speed | Transfers are faster in general.

| ^ [[resume|Transfer resume]] | Unsupported. | Supported. WinSCP supports resuming only since protocol version 2 (which introduces rename command). By default it resumes transfers for files larger than 100 kB only, since the overhead is excessive for smaller files. It is possible to change the threshold in Preferences. | | ^ [[resume|Transfer resume]] | Unsupported. | Supported.

| ^ Text (ASCII) [[transfer_mode|transfer mode]] | Not supported by protocol. WinSCP emulates text mode by converting file before transfer.

| - | ^ Directory operations | 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. | Recursive operations with directories (deletion, permissions change) must be performend separately for each file. Thus operations can take a long time, especially for directories with large number of files. | | + | ^ Directory operations | Recursive operations with directories (deletion, permissions change), can be done with a single command (''rm'', ''chmod'', etc).

| ^ Influence of environment variables | As WinSCP uses shell, it is influenced by environment variables (date format, etc.). WinSCP requires English environment. See [[requirements]]. | Generally unaffected by environment variables. | | ^ Influence of environment variables | As WinSCP uses shell, it is influenced by environment variables (date format, etc.).

| - | ^ File modification [[timestamp|timestamp]] | 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 timestamp of the file can be different. Also there can be additional difference caused by server timezone offset. This causes trouble when comparing directories and [[task_synchronize|synchronization]]. | Theoretically problem does not occur as the protocol requires timestamps to be in UTC. Practically some of the SFTP servers have problems with DST. | | + | ^ File modification [[timestamp|time-stamp]] | Some shell commands are influenced by daylight-saving time.
