(Excel) Controlling Paths of Files Added to Zip

When appending files to a .zip, it can be difficult to get the paths exactly as you want them. This example describes a way that you can control the path information when adding a single file at a time to a .zip.

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

Dim zip As Chilkat.Zip
Set zip = Chilkat.NewZip

' Intialize the zip object by calling NewZip.

success = zip.NewZip("myZip.zip")

' Add a reference to a file on disk to the zip object.
' (When appending files to a zip, the files are not actually
' read into memory.  References to the file(s) are added.
' When WriteZip is called, the referenced files are streamed in
' and compressed to the .zip.)

saveExtraPath = False
success = zip.AppendOneFileOrDir("/temp/a/hamlet.xml",saveExtraPath)
' For brevity, this example will not check the return status...

' The saveExtraPath argument, if set, will cause the path information
' passed in the 1st argument to be saved in the .zip.

' To add "a/hamlet.xml", do this:
zip.AppendFromDir = "/temp"
'  The saveExtraPath argument, if set, will cause the path information
'  passed in the 1st argument to be saved in the .zip.     But the path in AppendFromDir is
'  not added to that path saved in the .zip.     If there is a path in AppendFromDir then the
'  path in the 1st argument must be relative, not preceded by a drive or \.
saveExtraPath = True
success = zip.AppendOneFileOrDir("a/hamlet.xml",saveExtraPath)

' To add "temp/a/hamlet.xml", do this:
zip.AppendFromDir = "/"
saveExtraPath = True
success = zip.AppendOneFileOrDir("temp/a/hamlet.xml",saveExtraPath)

' The zip written here will contain hamlet.xml three times,
' each with a different relative path.
success = zip.WriteZipAndClose()
