// bbb/base64Cert.txt
// bbb/sub1/brasil_cert.pem
// bbb/sub2/penguins.gif
// bbb/sub2/starfish.jpg
// hamlet.xml
// hello.pdf

// then after unzipping, the following files will be created:

// c:/temp/testDir/aaa/pigs.json
// c:/temp/testDir/bbb/base64Cert.txt
// c:/temp/testDir/bbb/sub1/brasil_cert.pem
// c:/temp/testDir/bbb/sub2/penguins.gif
// c:/temp/testDir/bbb/sub2/starfish.jpg
// c:/temp/testDir/hamlet.xml
