VSD saves before upload as a precaution. It will upload only what has changed but has to scan your files and the website to compare them to see what needs to be uploaded.

Thanks for that clarification Eric.

So if I use the upload feature that's embedded in VSD only the changed files will be uploaded. If I want to use the DirectFTP application instead I won't be able to tell what's changed and what hasn't since they all have the same date/time stamp. Have I got that right or is there a way around that?
