In templatedata folder, we have category type, datatypr and in datatype we have datacapture.cfg. Now when I click on new form entry, datacapture.cfg generates new form template.We have mant other folders at the templatedata level like iw-web. Therr is no datacapture.cfg in this folder. So whats the use of these folders ? Why do we need to create these folders ? May be one folder we can create for preview but why do we need so many ?thanks
