If time is not on your side and you need to accomplish something related to archives in a short amount of time, then UnPacker is a good solution for you. Do not treat this tool as a replacement for classic archive extractors as WinRar or WinZip. They are okay to use when you only extract one or to archives, but with tens or hundreds, the solution is other.
UnPacker allows you to simply select all of your required archives to extract and add them to a list. From there, the software will take them one by one and extract them into a predetermined location. This is an automatic process that will save you a lot of time.
