The purpose of this dialog box is to enable or disable Design Notes for a site.
If you select this option, you can share Design Notes with the rest of your team. When you put or get a file, Dreamweaver automatically puts or gets the associated Design Notes file.
If you do not select this option, Dreamweaver maintains Design Notes locally but does not upload them with your files. If you work alone on your site, you can deselect this option to improve performance of file transfers.
A dialog box appears, asking if you would like to delete existing Design Notes files.
Design Notes will not be transferred to the remote site when you check in/put your files. You will still be able to add and modify the Design Notes for your site locally.
