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

    destroy loo_Zip

// Create a string array object with our set of filename patterns
// to be excluded:
loo_Sa = create oleobject
li_rc = loo_Sa.ConnectToNewObject("Chilkat.StringArray")

li_Success = loo_Sa.Append("*.bak")
li_Success = loo_Sa.Append("*.tmp")

// Tell the zip object to use these exclusions:
loo_Zip.SetExclusions(loo_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.
li_Recurse = 1
li_Success = loo_Zip.AppendFiles("/temp/a/*",li_Recurse)

if li_Success <> 1 then

    destroy loo_Zip

Write-Debug "Zip Created!"
