What is a DWSUPLOAD file? A DWSUPLOAD file is a partially uploaded file that stores the contents of a file a user transfers from one device to another with DWService, software that allows users to remotely connect to their home computer. The .dwsupload extension is temporary; DWService removes it once the upload is complete and replaces it with the extension of the file the software is transferring (the .dwsupload extension remains if the transfer is interrupted).

More Information Through DWService, you can install DWAgent on your home computer, which allows you to access and control your home computer from any location using a web browser. For example, you could be on a work trip in another country but need to access work files on your home computer. DWService allows you to access the files and folders on your computer and send them to your work laptop. When transferring files through the software, DWService creates a placeholder file with the .dwsupload file extension while the file transfers and then replaces it with the file it is transferring.
