| WinSCP needs to know what environment variable contains exit code of the last command. By default it tries to autodetect that. However the autodetection can fail and also slows down login. You may specify the variable directly instead in //Return code variable// box. | WinSCP needs to know what environment variable contains exit code of the last command.

| - | When the //Ignore LS warnings// checkbox is ticked, WinSCP will ignore any error messages printed by the ''ls'' command as long as it produces some regular output too. It also makes WinSCP ignore exit code ''1'' of the command. The option was added primarily to override ''pagefile.sys'' access-error produced by [[&opensshwin|OpenSSH for Windows]] whenever root directory was opened.

| The //Try to get full timestamp// makes WinSCP attempt to use ''%%--full-time%%'' option for ''ls'' command. It is particularly useful when you want to use some [[task_synchronize|synchronization]] command, for what you need precise timestamps. When it is ticked, WinSCP will add the option to the first ''ls'' command it issues. When the (first) command fails for whatever reason, WinSCP will stop using the option for the whole session. However in some cases WinSCP may fail to detect that the command failed. Then you need to disable the feature manually. | The //Try to get full timestamp// makes WinSCP attempt to use ''%%--full-time%%'' option for ''ls'' command.

These are: ''LANG'', ''LANGUAGE'', ''LC_CTYPE'', ''LC_COLLATE'', ''LC_MONETARY'', ''LC_NUMERIC'', ''LC_TIME'', ''LC_MESSAGES'' and ''LC_ALL''.

| WinSCP uses ''scp'' command to perform the transfer. On some SSH servers, particularly ssh.com, the ''scp'' may be a link to ''scp2'' command. The ''scp2'' is in fact SFTP server, that WinSCP cannot talk to in SCP mode. Check //Use scp2 with scp1 compat.// to make WinSCP try to force the ''scp'' command to use really the SCP protocol (using ''-1'' option). Note that if the server supports ''scp2'', it probably supports [[sftp|SFTP protocol]] too. | WinSCP uses ''scp'' command to perform the transfer.
