Windows 7: Windows 7 adding .jpg xtension to my files and documents

I am very frustrated that Windows 7 adds the .jpg xtension to many of my files which are for example:
Adobe InDesign files
Photoshop PSD files
Camera RAW files
Adobe PDF file

Can anyone please tell me how I can prevent Windows from doing this? I archive my files according to the program they are created in and I need to keep all my with file original xtension.

I use adobe bridge so I do not need to view the contents of my files in any Windows Explorer window.

If anyone can help me with this I would be most grateful! Many thanks

Hi and welcome to the Forrum.
When you say Windows adds the jpg extension to the file do you mean you get a pdf file showing as Filename.pdf.jpg or filename.jpg? When did this problem first appear and exactly what did you do immediatelly before it happened?

Yes, my file extensions are:
.indd
.psd
.pdf
.raw

windows adds:
.indd.jpg
.psd.jpg
.pdf.jpg
.raw.jpg

I am not sure if I am doing this right as I am new to the forum.

In reply to mitchell65, windows is adding an additional extension to all of my document files, ie: InDesign file would be flyer.indd. Windows 7 adds a .jpg extension so the file becomes
flyer.indd.jpg.

I know WHY windows is doing this, it is doing this because it thinks I want to see the actual content of my file in Windows Explorer. I don't need to see the content of the file and it,s very annoying! I use an application called 'Adobe Bridge' to view and work with my files.

Please, please does anyone know how I can stop windows 7 from doing this, if no one know this then I wonder if I could be pointed to another resource to solve this problem.

Any help would be much appreciated

Thank you

...You must have something installed or made some kind of change because this is most certainly not normal behavior, Windows itself is not going to change file extensions unless you or an application that you installed tells it to.

NO that is definitely not the case. Windows 7 will not dd a file extension unless as Logicearth says, you have used a program that tells Windows to do this. This is why I asked in my last post "When did this problem first appear and exactly what did you do immediatelly before it happened?" Can you reply to this please and say whether you have an up to date AV installed. Just as a precaution download and run Malwarebytes from here:
Malwarebytes

Scroll down a bit to get to the free version.

BTW You show the Union Flag for your country yet your timezone is set for the USA. Is there a reason for this?

Thank you. This is very strange indeed. I cannot think which application would cause windows 7 to do this. 90% of my software is Adobe Software, some are windows apps the rest are utilities such as SnagIt.

Would looking through the Control Panel help? I will take a look through my installed software

Thank you for your time and help.

Have you run Malwarebytes and can you answer all of my post pease? It is very important to know when this first happened! Was it a after a Windows Update perhaps?

No, I don't know what Malwarebytes is. I noticed this happening soon after I bought a laptop with Windows 7 on it. Could be around 2007 (ish). Is it possibile to upload an image of the files to the forum?
Thanks again
