When you use Dreamweaver's synchronize feature or upload files to a server, the following problems may occur:
- You are putting files and Dreamweaver is warning you that the remote file has changed on the server: "my_file.htm has changed on the remote server since your last get or put operation. Putting it may overwrite changes to the file. Do you wish to put the file anyway?" However, you are sure that the remote files haven't changed.
- The Synchronize preview dialog box is not correctly listing the files that should be synchronized.
- The Synchronize preview dialog box says that no synchronization is necessary, but you know that some files have changed.
Note: These issues apply only to Dreamweaver 8 and later. The synchronize feature was redesigned in Dreamweaver 8, so the troubleshooting steps mentioned here do not apply to Dreamweaver MX 2004 and earlier.
In Dreamweaver 8 and later, whenever a user puts or gets a file, Dreamweaver locally stores the remote and local date/time stamps in files called dwsync.xml, which are located in hidden _notes folders in the same folder as the files being transferred. Occasionally, the dwsync.xml files can get corrupted.
If you are having synchronization problems with just a few of your files, try deleting the specific dwsync.xml files (instead of re-creating all the synchronization information for your site):
If you are experiencing widespread synchronization problems, you can temporarily turn off the "Maintain synchronization information" setting so that Dreamweaver re-creates all the synchronization information for your site:
