The file extension DWS is used for site cache files of the web page editor Adobe Dreamweaver. Dreamweaver creates a folder and a DWS file with the site name under 'C: UsersNutzernameAppDataRoamingAdobeDreamweaver XConfigurationSiteCache' for each new site. The DWS file stores data about all links to files such as images and videos. The cache file is used during the development of a web page for faster access to the files.
If a DWS file is damaged, the program may support the access to the site. Remedy here is the deletion of the DWS file, because Dreamweaver this simply rebuilds.
