When you have a multi-layered Photoshop document and for whatever reason you want to save each layer as a separate document, it’s quite easy to do – and requires no tedious cut & paste commands. 
Go to File>Scripts>Export Layers to Files. When the dialog box appears, you’ll have several options available including where you want to save the files, and a file name prefix.
