To edit DT1 file, we strongly recommend installing software that works with DT1 files. There are many tools known as DT1 Online Editors, but it is not certain that they operate in a way that keeps the data contained in the file safe.
Please note that not every program that supports DT1 will allow you to edit the file. Additional information about the DT1 file extension can be found here.
