Some users have reported trouble importing their Dreamweaver site settings. One important thing to remember is that differing file structures on Macintosh and Windows machines can often cause this problem.
When you export a Dreamweaver site to an .ste file, that .ste file stores not only the FTP settings for your site, but also local file settings. The native file structure on Windows is completely different from that on Mac OS. The Import and Export features in Dreamweaver enable you to move site definitions from one computer to another (for example from XP to Windows 7), but not from one operating system to another.
The solution: Since .ste files are XML documents, you can open them and edit the attributes in the <localinfo> tag to match the new folder structure on your Mac or Windows machine.
