How do I delete a My Checkbook 2.x account?
Your My Checkbook accounts are stored, by default, in your "Documents" ("My Documents" on Windows XP) folder in the "My Checkbook Accounts" folder. To delete an account in My Checkbook, simply locate the account you wish to delete on your computer and move it to the trash (like you would any other file). Make sure and do this while My Checkbook, and that account, is closed. To delete an account in 3.x, just select the account in the account list, and choose "Delete Account" from the File menu. This cannot be undone.
