The purpose and contents of a .di_ file cannot be determined from the extension alone. There is no confirmed vendor, application, platform, or documented format association for it.
Because the format is unidentified, it is not possible to describe its relationship to other files or determine whether it is still in use.
No known program is associated with the .di_ file extension. It should not be opened or renamed with a particular application unless the source of the file identifies the software that created it.
No reliable conversion method is available for an unidentified .di_ file. Conversion requires first identifying the format and the software that created it.
