The purpose of this dialog box is to preview the actions Dreamweaver will perform to synchronize the files, and to change one or more of these actions if you want.
If the action icon is grayed out, the action cannot be performed.
The Compare action works only if you installed and specified a file comparison tool in Dreamweaver. For more information, see Comparing files for differences.
The Mark Selected Files As Already Synced button lets you tell Dreamweaver that the selected file or files are already synchronized.
You can view or save the details of the synchronization to a local file. For more information, see Managing file transfers.
