Zip Function for adding sub directories

[tim.calderwood]

I am using the built in Zip function and have the following directory structure.

C:\
CodeDir\
ProgramA\
ProgramB\
ProgramC\

I want to zip up sub folders ProgramA and ProgramC but want to exclude ProgramB. I have set the source folder to C:\CodeDir. I then tried excluding ProgramB\*.* but this zip everything including ProgramB. Therefore, I then tried including just ProgramA and ProgramC but this did not zip anything. The option is set for including sub folders.My questions is how can I just zip ProgramA and ProgramC without including ProgramB?

As a side question, what is the benefit of “Append to existing file (don’t use temporary file)”? I can not find anything in the help about this option.

Thanks ahead of time...
