WinRAR Switch -F - freshen files

Switch -F - freshen files

May be used with archive extraction or creation. The command string "a -f" is an equivalent to the command f. You could also use the switch "-f" with the command m.

If the switch "-f" is used with the commands x or e, then only old files will be replaced with new versions extracted from the archive. Archived files, without a matching unpacked file, will not be extracted.

The shell mode equivalent of this switch is the "Fresh existing files only" option in the Archive name and parameters dialog and "Fresh existing files" option in the Extraction path and options dialog.

Supported only for RAR and ZIP formats.
