Directory copy using InitiateFileTransferToGuest ??

Hello experts,

I do have the question related to the FileOperation using the vSphere API.

Q: How can we use the InitiateFileTransferToGuest() to upload the directory  ?

- Do we have to browse through the directory and get the list of the files. Then recursively call the  InitiateFileTransferToGuest() and http function to upload each individual files ??/???

Is there any better way of doing it ? or API available ?

- How to handle the symbolic link files  ?

Appreciate your help.

Thanks.
