How to control the paths stored within a .zip. Lianja

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

loZip = createobject("CkZip")

// This is the directory structure on the local filesystem
// from which we'll create .zip archives:
// The root directory is /temp/filesToZip
// 
// We have these files:
// /temp/filesToZip/faxCover.doc
// /temp/filesToZip/exe/Setup.exe
// /temp/filesToZip/images/cheese.jpg
// /temp/filesToZip/images/dude.gif
// /temp/filesToZip/images/img3.gif
// /temp/filesToZip/images/img4.gif
// /temp/filesToZip/images/img5.gif
// /temp/filesToZip/images/scream.jpg
// /temp/filesToZip/images/imageInfo/scream.xml
// /temp/filesToZip/images/imageInfo/cheese.xml
// /temp/filesToZip/text/html/bonaireFishing.html
// /temp/filesToZip/text/html/upload.html
// /temp/filesToZip/text/txt/hello.txt
// /temp/filesToZip/text/txt/HelloWorld123.txt
// /temp/filesToZip/text/xml/hamlet.xml
// /temp/filesToZip/text/xml/pigs.xml

// There are three properties to help control the paths stored
// within a .zip:
// AppendFromDir
// PathPrefix
// DiscardPaths
// 

// First we'll demonstrate AppendFromDir
// When a directory tree is appended via AppendFiles or
// AppendFilesEx, the AppendFromDir sets the base of the 
// directory tree appended (if the file pattern contains a 
// relative path, or no path at all).

// Clear the zip object.

// images/imageInfo/cheese.xml
// text/xml/hamlet.xml
// text/xml/pigs.xml

// xml/pigs.xml

llSuccess = loZip.WriteZipAndClose()
if (llSuccess <> .T.) then
    ? loZip.LastErrorText
    release loZip

endif

// The PathPrefix property adds an arbitrary path prefix to each
// file in the .zip.
// For example:

// Clear the zip object.

// For example:
