Mystery File mager.onnxe 300,597,649 bytes

Hello, Robert here, today I found a fairly large file of weird and puzzling origins. It's Called Mager.onnxe. and its 300,597,649 bytes and growing. It's located in system information files here 

I'v tried to find info on it and most I got from researching it was "is it missed spelled" for Maniger.one, copilot knew nothing about the file and then rewording my question in a way to make fun of it, (copilot hates this) it replied , ONNX stands for Open Neural Network Exchange. It’s an open standard for machine learning interoperability1. ONNX defines a common set of operators - the building blocks of machine learning and deep learning models - and a common file format to enable AI developers to use models with a variety of frameworks, tools, runtimes, and compilers, however copilot completely denies knowing or finding anything about this file, being owned created and secured by "SYSTEM" on my pc. i even did a forced web search "great for when ai, or copilot is being to stubborn to chatty, or having an AI hallucination"

 its reply, 

I’m sorry for the confusion earlier. I tried to find information about a file named “mager.onnxe” in Windows, but I couldn’t find any relevant information. It’s possible that this file is not a standard part of the Windows operating system or any commonly used applications.

The file size you mentioned, 300,597,649 bytes, is quite large (around 286 MB). If you’re not sure what this file is, it’s generally a good idea to not open it until you can verify its contents. Here are a few steps you can take to investigate further: Based on the directory listing you provided, it appears that the mager.onnxe file is located in the same directory as several other files related to the Photos App in Windows. This includes various .dll, .winmd, and .exe files, which are typically associated with Windows applications.

The mager.onnxe file could be a part of the Photos App or a related component, but without more specific information, it’s hard to say for certain what its purpose is. The .onnxe extension is not a standard file extension recognized by Windows or common applications. It’s possible that this file is used internally by the Photos App or a related component.

My Windows 10 has that file, with exactly the same size, in that folder as well.

I don't believe that there's anything sinister going on so you should stop worrying about it - especially when 286MB is hardly a big file.
 

BC has certainly taken me to some strange places on my computer !  This is not an area I have ever looked at but under WindowsApps there are any number of folders with the suffix '_8wekyb3d8bbwe' and '-8wekyb3d8bbwe' but I don't appear to have any file with the ONNXE extension. I would also have to disagree with Secret-Squirrel when he calls 286MB 'hardly a big file'. 286MB is about 40% of the capacity of a standard CD or equivalent to about 10 minutes of high definition (1020p) video.

All I can suggest, if you are worried about this being malicious, is to start a topic in Virus and Malware Removal.

Well, I had another look on a second PC and this what I found:

It's just a Photos app system file and nothing to worry about. I still don't believe that there's anything sinister going on or it's malware related.

I also checked my desktop-only computer with Microsoft Windows 10 Professional 64-bit Build 19045.4651 (22H2) and I have the same file, with the exact same file size, and in the same folder.

As a security and web browser enthusiast, I even follow the Best Practices for Safe Computing - Prevention of Malware Infection, so there is NO malware on my computer.

Hello,
Despite this being an old topic, I decided to bump it. Since there is very little information about this file on the web and it's huge, let's change it, as I did some digging.

"mager.onnxe" is an ONNX model for a component of a Microsoft project called Perceptive Shell. It is accompanied with a library, magerapi.dll. Lookng around it quickly shows that "mager" is an abbreviation for... "Magic Eraser". Which is an internal name for a Microsoft Photos feature, called Generative Erase.

Here's some docs: https://support.microsoft.com/en-us/windows/using-generative-erase-in-microsoft-photos-e0b4df42-3372-4dfd-9d28-c4ef408454a7
