Opening NOLS Files

NOLS	File extension: NOLS
	File type:	data container file

What is a NOLS file?

NOLS files mostly belong to PDF Reader. A NOLS file is not a single, standard file type but a container that can hold different kinds of internal data.
For example, one use is as a PDF metadata container that stores extra information for a PDF file. In other cases, the file acts as an encrypted file that may be used as a sidecar in image workflows, as seen with Nikon Capture NX2, or as an encrypted archive using a ZIP structure found in certain security applications.

PDF metadata file: Contains detailed data linked to a PDF document.

Encrypted image sidecar: Works with JPG files and is sometimes used with tools like Nikon Capture NX2 and Nokia PC Suite.

Encrypted archive container: Uses ZIP format and is associated with security software such as Norton Total Security.

FilExt.com notes: To open a NOLS file, try a PDF viewer for metadata purposes. If it is encrypted, use the software that created it or check the file header with a hex editor. More details can be found on the NOLS website.

How to open NOLS files

You need a suitable software like PDF Reader to open a NOLS file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your NOLS file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a NOLS file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert NOLS files:

PDF Reader
See the previous paragraphs to learn more about the main application. NOLS files are often referred to as PDF Reader data files because this type of file is primarily created or used by this software.
Norton Security Products/Nikon Capture NX2/Nokia PC Suite
A *.NOLS file is likely an encrypted archive, often a *.ZIP file, containing sensitive data. It's primarily associated with Norton products, potentially for backup or secure storage purposes. Less commonly, *.NOLS might refer to Nikon or Nokia sidecar files, containing metadata or supplementary information related to image or other file formats. Note: Files with the .NOLS extension are often associated with ransomware infections. This type of malware encrypts files on a victim's computer and appends the .NOLS extension, rendering them inaccessible without a decryption key. Attackers typically demand a ransom in exchange for this key. You may find decryption tools on NoMoreRansom.org.It is strongly recommended that you do not pay the ransom. Doing so does not guarantee file recovery and only encourages further criminal activity. Instead, report the incident to law enforcement and seek assistance from cybersecurity professionals. This file format is classified as Encrypted Archive/Sidecar File.

NOLS file extension format:

Every file has a defined file format, i.e. how the data is arranged in the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our examination of the NOLS files comes to the following conclusion:

The NOLS file extension is rarely used and covers different formats for different programs. But the following two file formats are common:

30% of all NOLS files save the data in PDF file format. PDF is short for Portable Document Format, is a file format to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. The contents of these files cannot be read by a human; only a computer program can interpret the data. The files are on average 6 MB in size and range from 250 KB to 11 MB. It is a modern file type. These files can be linked to coperta, medicina, istorie, contemporani, desfasurata, puritatii, scriitori, medici, poezia and areal, and often include person-related information.
25% of all NOLS files store the data in the JPG file format. JPEG is the standard image format for lossy and compressed image data. They consist of illegible, cryptic characters. NOLS files can be up to 4 MB in size, but are often around 39 KB - 2 MB. The following filename is common: 20180601.jpg.nols.

All the rest of the NOLS files (45%) have different formats, the following 5 formats can be found: ZIP and RIFF. The category is revista, arheu, mijloc, docx, iunie or xlsx.

How to solve problems with NOLS files

Associate the NOLS file extension with the correct application.
Update your software that should actually open data container files. Because only the current version supports the latest NOLS file format. Search, therefore, e.g. on the manufacturer website after an available PDF Reader update.
To make sure that your NOLS file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
