How to open DLT files

Did your computer fail to open a DLT file? We explain what DLT files are and recommend software that we know can open or convert your files.

What is a DLT file?

DLT files are DELTA binary dataset files, which you can read more about below.

The DLT file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So a DLT opener may not be able to open all kinds of DLT files. In this case, though, we only know of one specific use.
