Windows command line compression/extraction tool?

I need to write a batch file to unzip files to their current folder from a given root folder.

Folder 0
    |----- Folder 1
    |      开发者_运维问答    |----- File1.zip
    |          |----- File2.zip
    |          |----- File3.zip
    |
    |----- Folder 2
    |          |----- File4.zip
    |       
    |----- Folder 3
               |----- File5.zip
               |----- FileN.zip

So, I wish that my batch file is launched like so:

ocd.bat /d="Folder 0"

Then, make it iterate from within the batch file through all of the subfolders to unzip the files exactly where the .zip files are located.

So here's my question:

Does the Windows (from XP at least) have a command line for its embedded zip tool? Otherwise, shall I stick to another third-party util?

AFAIK, there is not unzip tool shipped as part of Windows XP, but there is gnu unzip which will do the job nicely for you.
