Files that contain the .tag file extension are ASCII files that are used by the DFQuery search string, which allows users to choose specific fields from a data file. These files are similar to FD files. They name the query or search string that is being used by the Data Access SQL.
These TAG files are normally created by the DataFlex and COREX software applications. DataFlex and COREX are object-oriented 4GL database programming languages.
Users can also use the TAG file format to render a MicrosoftTag, allowing them to create a hexadecimal code to generate the tag in other applications.
