How to create a .zip archive excluding (skipping) files that match a set of wildcarded patterns. PowerShell

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

$success = $false

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

$zip = New-Object Chilkat.Zip

$success = $zip.NewZip("test.zip")
if ($success -ne $true) {
    $($zip.LastErrorText)
    exit
}

# Create a string array object with our set of filename patterns
# to be excluded:
$sa = New-Object Chilkat.StringArray
$success = $sa.Append("*.bak")
$success = $sa.Append("*.tmp")

# Tell the zip object to use these exclusions:
$zip.SetExclusions($sa)

# Append a directory tree.  The AppendFiles does
# not read the file contents or append them to the zip
# object in memory.  It simply appends references
# to the files so that when WriteZip (or WriteZipAndClose,
# or WriteExe, etc.) is called, the files are compressed
# and encrypted.
$recurse = $true
$success = $zip.AppendFiles("/temp/a/*",$recurse)

$success = $zip.WriteZipAndClose()
if ($success -ne $true) {
    $($zip.LastErrorText)
    exit
}
