This can be configured on //[[ui_pref_resume|Resume tab]]// of Preferences dialog.

| The above method of resuming file transfers is supported only for [[protocols|SFTP version 2]] and newer (most of the current SFTP servers). There is another method supported even for the older servers (but not for SFTP version 4 and newer for ASCII/text transfers). Even if your server supports SFTP version 2 and never, you may find the method useful. Note that you must have [[ui_pref_environment#confirmations|overwrite confirmations]] enabled to use the method. | The above method of resuming file transfers is supported only for [[protocols|SFTP version 2]] and newer (most of the current SFTP servers).

| - | When you attempt to transfer file that already exists in target directory, the overwrite confirmation dialog is displayed. It offers //Append// button. By default it appends source file to the end of the target file. But if the target file is smaller then the source file, another prompt will be displayed offering you either to append source file or to resume transfer. If you select to resume transfer, the part of source file equal to size of the target file will be skipped and only the remaining part will be transfered. | + | When you attempt to transfer file that already exists in target directory, the overwrite confirmation dialog is displayed.

| It is on user responsibility that he/she resumes transfer with the same version of source file as the transfer was interrupted. Otherwise you will end with target file consisting partly of previous version and partly of current version of the source file. If the partial file is bigger than the source file, WinSCP will display error and disallow resume. | It is on user responsibility that he/she resumes transfer with the same version of source file as the transfer was interrupted.
