Thanks for the quick response. I suppose it would make your life easier if I posted the error message! For some reason I can't add "home". Works great otherwise.
Error: Wrong number of arguments or invalid property assignment.
Here is the code: (that is a comma preceding "home" )
filename = "C:\Temp\test.zip"
set zip = CreateObject("Ionic.Zip.ZipFile")
zip.Encryption = 3
zip.Password = "TEST"
zip.AddFile "C:\Temp\test.xls", "home"
zip.Name = filename
