How to Delete a Path in Photoshop
If you no longer need an Adobe Photoshop CS3 path or an object created as a path, you can delete the path in a few steps. The path is deleted by removing the entire path layer from the Paths palette.
Start Adobe Photoshop CS3 and open an existing document from your files that contains a path you would like to delete.
Choose the "Window" menu, and click "Paths" to bring up the Paths palette, if necessary. The Paths palette shares a window with the Layers and Channels palettes. All of the paths you have created in the open Photoshop document will be displayed as separate path layers in this palette.
Select the path layer from the Paths palette that contains the path you want to delete. The layer will become dark gray once it is selected.
Click and drag the layer to the bottom of the Paths palette, right over the "Delete current path" button. This button is on the very bottom right side of the Paths palette and is represented by a picture of a trash can.
Release your mouse button when the "Delete current path" button is indented. The path layer along with the actual path will automatically be deleted from the Photoshop document.
