On Dreamweaver CS5 on Win10, the site panel filelist shows folders but no files. On Win7 and previous versions, it showed files. Is there a way to display files on Win10?
CS5 is discontinued & unsupported software from 2010. Forgive me for saying this but nobody should be using outdated web authoring software. The Internet has changed too much. Equipment and operating systems have changed significantly, too.
To your question, can you see files in your local site folder with Windows File Explorer?
Have you tried creating a new site definition that points to site files on your primary hard drive?
[Given that CS5 is not supported, moderator moved this from Bugs to Discussions.]
