Switch -CL - convert file names to lower case

When this switch is used, names of all files extracted from an archive, added to an archive, modified or updated within an archive, will be converted to lower case. This is sometimes useful when moving an archive from a case insensitive OS to a case sensitive OS, for example, extracting in Unix system an archive created in DOS.

Example

extract all files from port.rar converting names to lower case

WinRAR x -cl port
