$zip = New-Object Chilkat.Zip

$success = $zip.OpenZip("qa_data/zips/test.zip")

# Iterate of each entry in the zip.
# An entry can be a file or directory entry.  For each file, unzip to a byte array.
$numEntries = $zip.NumEntries
$("NumEntries = " + $numEntries)

$entry = New-Object Chilkat.ZipEntry
$i = 0
while ($i -lt $numEntries) {
    $zip.EntryAt($i,$entry)
