At least once since you had your computer, you were required to use the finder tool integrated in Microsoft Windows. The bad part is that not always the tool will give you results good enough, as I happened to find certain files after the search tool could not help me. This is the case of archives, too.
ZipScan gets over this disadvantage of the finder tool and searches more thoroughly through the computer, listing you every archive that you are looking for, in different formats. The classic formats are not even to be mentioned, but ZipScan also searches for TAR, JAR or ARJ archives.
