# In this example, the xml_files.zip contains some files in the subdirectories "dir1" and also "dir2/dir3".

# a1.xml

# c1.xml
# dir1/a2.xml
# dir1/c2.xml
# dir2/dir3/c3.xml

$("Num unzipped = " + $numUnzipped)

# After unzipping via UnzipInto, we have this:

# c:\temp\testUnzipDir\a1.xml

# c:\temp\testUnzipDir\a2.xml
