Extract text from update packages (NUP)
To convert NUP updates to another format, you need Norton AntiVirus or other Compressed software.
To convert other file formats to the "Archive and Update File" file type, you need software like Norton AntiVirus or a similar tool.
.NUP files serve two very distinct primary purposes in the real world. They are either game data archive packages used by the Capcom MT Framework engine to bundle 3D models, textures, and sounds, or they are Norton Update Packages (and sometimes ESET Smart Security updates) containing offline virus definitions. Gamers usually encounter them when modifying PC game files, while IT administrators download them to update enterprise computers disconnected from the internet.
The main disadvantage of .NUP files is their highly proprietary nature. Standard archive managers like WinRAR or 7-Zip cannot open them. Norton update files are heavily packed and digitally signed to prevent tampering. Meanwhile, Capcom archives use a specialized, undocumented indexing system optimized for rapid rendering rather than accessibility. Because of these strict internal structures, you cannot simply rename the extension to ZIP and expect it to work.
When handling the game archive variant, users typically want to extract the contents to standard formats like PNG or DDS for textures, or OBJ for 3D models. Standard online converters fail completely here because they lack the specific decryption algorithms or proprietary extraction logic needed for these niche formats. Often, only community-built modding scripts or the original game engine can properly parse the data. However, you can drag and drop your file into convert.guru to identify the exact format signature, inspect the hexadecimal headers, and view embedded plain text. If our analysis detects a supported underlying compression method, viewing or partial conversion may still be possible.
Convert.Guru analyzes your NUP file, detects the exact format, and lets you read the text inside.
Users also converted NG, NIL and _DD files.
If you want to convert NUP file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, LOCK or PID, you can use Norton AntiVirus or similar software from the "Archive or Security Update" category. In the File menu, look for Save As… or Export….
To convert DEVICE, CACHE, SOCK, SYMLINK, PID, MOUNT, FIFO, LOG, PIPE, TMP, JUNCTION or TEMP files to NUP, try Norton AntiVirus or another comparable tool in the "Archive or Security Update" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NUP converter.
