I often get to download multi-part zips / rar files; where a single large file is divided into 2-3 archives. For example, movie-xyz.part1.rar, movie-xyz.part2.rar, movie-xyz.part3.rar. Right now, SE doesn't support this and throws an error saying the file is in unsupported format when I tap on any of the rar. On windows PC, these rars are easily extractable, generating a single file at the end. It would be greate if SE can do it too.
