Windows 10: Random 10GB file without extension

I was looking in one of my own created folders, and I saw this file named s2jo.


No extension at the end. When I tried opening it, it gives me a variety of options Notepad, Visual Studio, etc. but they all can't open it and give errors like "File can't be found."


I tried deleting this file but it just says:


Could not find this item. This is no longer located in the path where I found it. Verify the item's location and try again.


I don't know how I'm supposed to verify it's location.


When I right click the file, then Properties, it says the Size is 0 bytes, but when I go to Details, it says it's 10.4GB. That's kind of alarming for some random file that takes up 10GB.


It says it was created on 3/27, and modified 6 minutes after creation. I don't remember what I was doing at the time, but I'm pretty sure I was on my computer at the time.


I searched up what to do with a file with no extension, and when I searched it up, I heard I should use a Hex Editor, so I got Freeware's Hex Editor and when I try opening it there, it says:


.s2jo

File not found. Check the file name and try again.


So now I came here, asking what I should do with this random s2jo. file.

• In the Word Options window, choose Save.
• Under Save files in this format, select *.doc from the list.

Can a file extension(.flv) be added to Default Program Associations.

Hi Fred,



Thank you for posting your query on Microsoft Community.



I understand that you are facing issues associating a particular file extension with a program on Windows 10. I apologize for the inconvenience caused to you.

To assist you better, please provide the information:

When you say that "Default Program Associations", are you referring to the list of default applications in default programs settings?



I want you to be informed that all the file extensions is listed in the default program settings which is displayed under
Associate a file type or protocol with a program.



In default program list, all the programs or application will be listed. Then we can select each program as default program for opening a particular file.

I suggest you to refer to the below steps to make default program for a particular file extension.

1. Type "Control Panel" without the quotes in search box and click on it.

2. Click on Programs.

3. Then click on Default Programs and click on Choose Default for this Programs.

4. Select .flv file from the list.

Also you can try other steps to associate the a particular extenstion with the program.

Your Firefox extensions are all disabled? That's a bug!

Thanks for the reply. I tried deleting LastPass, re-booted my computer, started Firefox and then re-installed LastPass as you suggested. I signed in to LastPass and then shut down Firefox. When I restarted Firefox it signed in to LastPass automatically so that problem remains.

And the Tools/Add-ons/Extensions list remains blank although now if I right click the LastPass icon in Firefox it takes me to the top position in the Extensions list (previously LastPass was #4) - so it seems Firefox isn't displaying the entries in the list but knows which ones should be there and their positions.

I never noticed a problem with extensions during this recent Firefox issue and the only obvious problem now is the automatic sign-in to Lastpass and the blank extensions list.

Update: The Extension list appears in Firefox's SAFE mode so it looks like my profile is damaged. Haven't had this happen before, could be random or something to do with the recent update....
