Using PC File Manager
Install PC File Manager on your PC. Connect your Sony Ericsson P800 smartphone with the PC (the appropriate PC Suite must be installed) and start PC File Manager. To start PC File Manager click the Windows Start button, point to Programs, and click File Manager icon in Epocware folder.
Then you can manage the files and folders on Sony Ericsson P800 from your PC in a standard way. You can:
Browse files and folders.
Cut, copy, paste files and folders.
Rename and delete files and folders.
Create new files and folders.
View properties of drives, folders, and files.
With PC File Manager you can also copy files between your Sony Ericsson P800 phone and the drives and folders on your PC.
In fact, you can use PC File Manager to perform most of the same tasks with the files on your phone as you can with files on the PC. Use the normal Windows techniques (drag and drop, right-clicking, etc.) to work with the files on your phone.
