About OPK files

OPK file types are used to package applications and games for the Nintendo DS, Nintendo 3DS, and Nintendo Wii U gaming consoles. These files are typically used to distribute applications and games to the gaming consoles, and are not meant to be opened or edited on a computer. OPK files are usually in a proprietary format, and thus require specialized software to open and convert them.

The two most common file extensions for OPK files are .3ds and .cia. The .3ds file extension is used for 3DS applications, and the .cia file extension is used for DS and Wii U applications. To convert these files, you will need software such as 3DSTool or Project CTR.

When converting OPK files, it is important to consider the type of file being converted. Different software may be needed for different types of OPK files, and some software may not support certain types of files. Additionally, some OPK files may be encrypted, making conversion more difficult.

Overall, OPK files can be difficult to convert, and the process can be time-consuming. For this reason, we recommend using the free and easy online website Convert.Guru to convert OPK files.


The OPK Converter Story

The history of Convert.Guru began more than 25 years ago in California, when Tom Simondi published the most comprehensive database of file formats on his website. Before that, Tom had worked on Space Shuttle development at the Air Force Systems Command’s Space Division in Los Angeles. He is known as one of the top programmers of the late 1980s.

When Microsoft integrated Tom’s Filext database into Windows XP, it became the leading platform for analyzing and processing file types and formats.

Today, we use the latest technologies to analyze, process, and convert one of the world's largest collections of file formats. We are committed to developing the best OPK converter by continuously improving quality, usability, and reliability.
