What is a QES file?

QES files mostly belong to QuestBack EasySurvey. The QES file is a questionnaire file that stores survey data using an internal JetDB format. It holds the structure of survey questions and user responses.
Such files are created by QuestBack EasySurvey systems (linked with Questback Essentials) and are meant to work with that specific software.
Use the file as follows:

Open it in QuestBack EasySurvey to view the questionnaire content

Export data using the software's built-in tools if needed

Keep a backup to avoid data loss

FilExt.com tip: This format is not plain text and should not be edited with general text editors.
