Here's what I need to do:

I need to move a jar file from windows to unix and be able to extract the
file in unix creating the directory structure. As you knwo, Windows uses
backslashes while unix uses slashes. When i extract the jar file in unix,
it does not create the directory structure and the files contain the backslashes
in the names.

Here's what I'm trying to do:

I create a jar file with the contents of three folders in Windows. Now I
want to update the jar file and for every file change the path property of
the file to revert the backslashes to slashes.
