batch file to make all sub-folders and their files writable

Hi, I'm not very good on writing batch files for Windows so please bear with me. What I want is a batch file which will make all sub-folders and their files writable.

The batch file would hold the paths to the directories I'd like to change. Something like:

c:\temp\folder1\
c:\temp\folder2\
c:\temp\folder3\subfolder1\
c:\temp\folder3\subfolder3\

Where I want folder1 and folder2 and all of their files and subfolders (and all of their folders and files, and so on) to be readable. And, for the next two, I'd only want subfolder1 and subfolder2 and all of their folders and files, and so on, to be readable. I wouldn't want c:\temp\folder3\subfolder2\ to be touched.

I know this sounds odd but this is how I need it to work. I have hundreds of files in hundreds of folders and instead of manually selecting the properties of each folder and changing the read\write check box it would be really nice to be able to just run a batch file. I know I can easily do this in Unix/Linux with chmod. I just don't know Windows scripting.

I'd like to be able to edit the batch file, add all of the directory paths that I need changed, save and close the file and run it. Maybe have it so that it doesn't dump out all of the files that are being updated.

Anyway, if anyone can help out, I'd appreciate it.

Thanks,
