What is a NONE file?

NONE files mostly belong to IrfanView. NONE files are files that use the JPEG internal format even though they lack a standard image extension.
When you open a NONE file, the system actually reads it as a JPEG image. Programs like IrfanView can detect the image’s internal signature even if the file name does not end with .jpg.
Key points summarized by FilExt.com:

The file contains JPEG data despite the misleading extension.

It is often the result of a renaming error or a system change that removes the proper extension.

Renaming the file from NONE to .jpg can help some software recognize it immediately.

Specialized image viewers can read the file by checking its internal header.

FilExt.com note: This file format is not a different image type but is simply a standard JPEG image that appears with a non-standard file extension.

How can I open a NONE file?

You need a suitable software like IrfanView to open a NONE 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 NONE file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a NONE file directly in the browser:. Just drag the file onto this browser window and drop it.

NONE file format:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. The file format can be deduced from the file extension and the signature. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our evaluation of the NONE files is as follows:

NONE is seldom used as a file extension and includes many different file formats. The two most common formats are as follows:

• 15% of all NONE files use the ZIP format, multiple files are compressed and combined into one NONE file. The average file count is 18 with most NONE files containing between 3 - 25 compressed files. Common included file names are [Content_Types].xml, \_rels\.rels, \customXml\_rels\item1.xml.rels, \customXml\item1.xml, \customXml\itemProps1.xml, \docProps\app.xml, \docProps\core.xml, \docProps\custom.xml, \xl\_rels\workbook.xml.rels, \xl\printerSettings\printerSettings1.bin, \xl\sharedStrings.xml, \xl\styles.xml, \xl\theme\theme1.xml, \xl\workbook.xml, \xl\worksheets\_rels\sheet1.xml.rels and \xl\worksheets\sheet1.xml. If you'd like to see the images and files included, just rename the file extension to .zip and double-click. The files are often between 31 KB and 180 KB in size. The following keywords are characteristic: [Content_Types].xml. A usual file name is 20180601_Planograma Eklenen_Planogramdan Cikan urun Listesi.NONE or 20180601_Deneme urun Listesi.NONE. These files are attributed to listesi, urun, deneme, planogramdan, planograma, eklenen, cikan, guncel, masraf and kart.
• 15% of all NONE files start with the bytes fLaC crucial for this file format. The contents of these files cannot be read by a human; only a computer program can interpret the data. NONE files are between 25 MB and 76 MB in size. Certain words are almost always found in the files, such as fLaC.

All the rest of the NONE files (70%) have different formats, often e.g. HTML, JPG, MP3, RIFF and PDF. The category is imageedit or temp. You can get all the details of your NONE file by dragging it onto this page or by clicking the button "Choose your .none file to analyze" above.
