FAQ During database modify I accidentally deleted a field in my list how can I get it back? When ever you use database modify, MAILERS+4 creates a back up of your list called "(your list name).bak". Just open the .bak file and your list will be back to it's original form. You will have to rename "(your list name).bak" to "(your list name).dbf" to be able to open the file again. Remember to delete your current file that is ruined, otherwise Windows will not allow you to rename the backup as 2 files in the same folder with the exact same name.
