Recursively unpack a collection of files, maintaining directory structure?

[Calab]

I have a collection of files, in a directory tree. They are in many ZIP and LHA formatted files.  I wish to unpack all the files, while maintaining the directory structure, to a different location.

Can someone suggest a simple script I can run that will do this?

The current tree looks like:

Code: [Select]

Maindir
   file1.zip
   dir1
      dir2
         file2.lha
         file3.zip
      dir3
         file4.lha
   dir4
      file5.zip
and should look like this after the script is run:

Code: [Select]

Altdir
   file1
   file1.icon
   dir1
      dir2
         file2
         file2.icon
         file2.readme
         file3
      dir3
         file4
         file4.info
         file4.dir
            file4.readme
   dir4
      file5

Sorry for the late reply... I'm not getting notifications for my posts.

Thanks for the suggestions. I scrapped the idea of unpacking all the files and will just unpack what I need when I need it.
