Zip a directory tree by calling WriteZip instead of WriteZipAndClose. When WriteZip is called, the created zip is automatically opened and the zip object contains references to the compressed zip entries (mapped entries) contained within the .zip. Visual FoxPro

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

loZip = CreateObject('Chilkat.Zip')

lcZipPath = "c:/temp/myFiles.zip"

* Initialize the zip object, which also sets the FileName property to the path of the zip to be created.
loZip.NewZip(lcZipPath)

* Append references to files to be zipped.
lnRecurse = 1

* Write the .zip, but don't close the zip file.
* The zip file we just created is automatically opened and the zip object
* now contains entries that are contained within the zip.  (They are memory-mapped entries)

* Let's look at what's in the .zip we just created..

lnNumEntries = loZip.NumEntries

DO WHILE i < lnNumEntries
    loZip.EntryAt(i,loEntry)

* Close the zip file when finished.
loZip.CloseZip()
