What is a .NUP file?

A .NUP file is a type of update file specifically used by ESET security software products. This file helps to update ESET Smart Security, which is a comprehensive security program designed to protect computers from various threats like viruses, spam, and spyware. The .NUP file includes important information such as the name of the update, the version and build of the software it is updating, the category of the update, the date it was released, the size of the file, and specific data related to the update module.

Although originally associated with ESET Smart Security, .NUP files are also utilized by other ESET products, such as ESET Cybersecurity for Mac. This indicates that both Windows and Mac users can encounter these update files when using ESET security solutions.

To open a .NUP file, you would typically use ESET Internet Security or ESET Cybersecurity for Mac, depending on your operating system. These programs automatically process the .NUP files to update the respective security software to the latest version, ensuring enhanced protection against new threats.

It's worth noting that ESET Smart Security has been succeeded by ESET Internet Security. This newer version offers improved features and multi-layered security, particularly for Windows users, enhancing their safety while browsing the internet. This transition means that the latest updates and support are likely focused on ESET Internet Security and other current products.
