[EpiData-list] Revise .epx-file structure during data entry?

Data has been entered into foo.epx. Some data could not be entered as values were outside accepted range. Thus, we have to revise foo.epx . How should foo.epx be revised in EpidataManager? By "open file" and revise variable structure or "import file" and....?
