Lingoes

Lingoes if a program for reading language dictionaries (AKA glossaries) with an emphasis on translation dictionaries, "often compared" to Babylon. It uses a dictionary format whose versions have the extensions ".lds" and ".ld2". There is a reference to a ".ldx" extension, apparently also used for the ld2 format ; this may just be a concise way of referring to both the extensions at once.

As of 2020, the last release of Lingoes was in 2014.
