JustExtractor is a shareware, it is uses to decompresses large amount of folders automatically. Imaging, if you have a folder, which preserve more than one hundred sub folder inside, and each sub folder includes countless compression files(ZIP or RAR, whatever), then I believe these might spend you half day to restore these compressed files. Thanks to the JustExtractor, now, you only have to point your root folder, then JustExtractor will automatic decompresses inside of several hundred sub folder, this is the main function of JustExtractor, it can save your valuable time. JustExtractor uses WinRAR to as decompress engine, so the speed of decompressed is quick and stable, so while before using JustExtractor, this won't work unless you install the WinRAR first.
