Everytime you preview a file, it creates a preview file copy within the incomplete folder. It will be called PREVIEW - ...... So after previewing or finishing downlding the file you should remove the preview files from the incomplete folder. If you're not sure where it is, go to LW's Library window, select the incomplete folder & press the Explore button. This will open the folder for you.

Personally, I prefer previewing from the incomplete folder so it doesn't create a preview file. Go to Library incomplete folder, find the file you're downldlng & press Launch.

When you've finished downlding files, go to your LW Library window, select Saved Files folder & press the Explore button. Sample image here: Using Library Explore button to access downld folder (click on link) & the folder will open up for you. That's easy & fast access to your downlds.
