Opening NUP files

Did your computer fail to open a NUP file? We explain what NUP files are and recommend software that we know can open or convert your NUP files.

What is a NUP file?

The .nup file extension is most commonly used by the ESET Nod32 anti-virus software. Files with the .nup extension contain update information for the anti-virus application. These updates are installed by the software to maintain up-to-date virus definitions and anti-virus protection.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
