What is a UDS file?

A .UDS file is a data file format that has several very different uses. Most often, it is an Ultimate Data Structure file used by older genealogy programs like Ultimate Family Tree to store family tree information. In the same category, it can also be a Sierra Generations File created by legacy Sierra software.

However, the .UDS extension is also used in science and engineering. It can be a Hitachi spectrophotometer data file, an automotive data reading script for the ELRASOFT UPA-USB Programmer, a Tachosoft UDS Manager odometer correction file, or a power supply design document for Power Integrations PI Expert.

How to open UDS files?

Because the .UDS extension is shared by many different applications, you must know what kind of file you have before you can open it. If it is a genealogy file, you may need legacy software or a conversion tool to read it. If it is scientific or automotive data, you must use specific hardware software like the Tachosoft UDS Manager.
