When we publish a form to S Drive, do we still need to upload the folder and PHP file to a website? I have client sites that I want to switch over to S Drive and don't want to make a mistake by deleting those files.

When you publish your form to S-Drive no other files are needed. Copy and paste the embed script that the form builder provides after publishing into your page and then test. After testing login to your CC account and go to your S-Drive dash board and check on your form stats.

I was adding the embed script to an html element on the page in RSD. Is it OK to do it that way also?

The form works with it like that.

I just wasn't sure it was OK to delete the folder and the one file we upload when we not using S Drive.

Thanks for letting me know.
