File Formats for the ZIP files

My class handouts and code are packed into a ZIP file using a standard
ZIP utility. Inside the ZIP are either text files or other ZIP files.
Sometimes, as in the very first file Class1.zip, there is an embedded
JAR file, which is a Java-generated subtype of a ZIP file. Any utility
that reads and unpacks a ZIP should be able to do the same with a JAR.
For anyone with Java installed, the command would be

               jar xvf Class1.zip
               jar xvf CCode1.jar

Unix-type systems and Windows have different conventions for text files.
It's possible that my text files may be single line on a Windows box. 
There are many sites and tools for conversions, among them:

   http://ccrma-www.stanford.edu/~craig/utility/flip/
   http://www.fileformat.info/convert/text/unix2dos.tr
   http://www.sg-chem.net/u2win/

Of course, I can't guarantee any of these: use at your own risk but they
seem fine from my simple testing.

My text files originate mostly from a Unix box because I use a helpful
utility to put in line numbers. It's important to resolve quickly any
glitches there may be in downloading, unpacking, and reading my files.
