A DELTA data set can be stored in one of three main formats:

The DELTA Editor program is able to convert between the ".dlt" and text/directive file formats. It is also able to produce a file in the Intkey ".ink" format, however it cannot convert an Intkey file back into one of the other two formats.

Internally, all formats are represented as an instance of a DeltaDataSet.

An example of how to produce a DeltaDataSet from the text file and ".dlt" file formats can be found at LoadingDeltaDataSets.
