Duplicating, deleting, or renaming layouts
You can duplicate, delete, and rename layouts in Layout mode.
 
From the Layout pop-up menu, choose the layout to duplicate, then choose Layouts menu > Duplicate Layout. You see the duplicated layout, and FileMaker Pro adds its name — with Copy appended — as the last choice in the Layout pop-up menu.
From the Layout pop-up menu, choose the layout to delete. Choose Layouts menu > Delete Layout, then click Delete in the alert message. You can't undo deleting a layout.
From the Layout pop-up menu, choose the layout to rename. Click Layout Setup Layout Setup button in the layout bar. (You can also click the name of the layout’s current table.) For Layout Name, type a descriptive name, then click OK.

You can't copy a complete layout to another FileMaker Pro file, but you can copy and paste all of a layout’s objects into a layout in another file. Select the layout objects you want to copy, and choose Edit menu > Copy. Then switch to the layout in the other file, and choose Edit menu > Paste. If field names are not identical in both files, you will need to respecify the field you want each field object to display.
