I am trying to extract a zip folder using 7zip from command line.

7z x "%BackupFileDestination%" -o"%ExtractDestinationDir%"

it is taking too much time to do so. Even hanging on few files. Any idea which switch if available can make the extraction quick like the one for compression -mx5.

The compression level switch allows to make a tradeoff between time and compression - compress the file quickly and end up with a potentially bigger file, or take your time and get a smaller file.

There's no switch to make extraction faster - why would anyone not use that switch?
