(PowerShell) Set Entry Filepath (in output Zip) when Zipping

Demonstrates how to set the path for the file entry within the .zip to something different than the path in the filesystem.

# When an absolute filepath is passed to AppendOneFileOrDir, the path within the .zip
# will be one of two values:  (1) just the filename part if saveExtraPath is $false,
# or (2) the full absolute path, but made relative, if saveExtraPath is $true.
# (For example, "c:/ck2000/appData/UnitTest/qa_data/hamlet.xml" made relative is 
# "ck2000/appData/UnitTest/qa_data/hamlet.xml")
$saveExtraPath = $false
$success = $zip.AppendOneFileOrDir("c:/ck2000/appData/UnitTest/qa_data/hamlet.xml",$saveExtraPath)
if ($success -ne $true) {
    $($zip.LastErrorText)
    exit
}

# When a relative path is passed to AppendOneFileOrDir, then saveExtraPath does not apply.
# For example, assume our current working directory is "c:/ck2000/appData/UnitTest".  The following
# call to AppendOneFileOrDir creates an entry with the filepath "qa_data/hamlet.xml".
$success = $zip.AppendOneFileOrDir("qa_data/hamlet.xml",$saveExtraPath)
if ($success -ne $true) {
    $($zip.LastErrorText)
    exit
}

# Examine the entries
$numEntries = $zip.NumEntries
$i = 0
while ($i -lt $numEntries) {
    $e = $zip.GetEntryByIndex($i)
    $([string]$i + ": " + $e.FileName)

    $i = $i + 1
}

# The output so far is:

# 	0: hamlet.xml
# 	1: qa_data/hamlet.xml

# If we write the .zip as-is, then the zip will have two entries
# with the filepaths as shown above.

# This writes "qa_output/zipA.zip"
$success = $zip.WriteZip()

# Now change the entry filepaths to whatever is desired.
$entry = $zip.GetEntryByName("hamlet.xml")
if ($zip.LastMethodSuccess -eq $false) {

if ($zip.LastMethodSuccess -eq $false) {
    $("entry not found")
    exit
}

$entry.FileName = "Shakespeare/Claudius2.xml"

# Change the name of the .zip to be written and write again:
$zip.FileName = "qa_output/zipB.zip"
