If you can....then take it as a matter of fact...there are small duplicate files of your RAW images, probably jpeg or Tiff.
Has nothing to do with whether PC, Mac or Linux or anything else.
It is impossible to just "see" an image in a RAW file. If you "see" an image, prior to processing, (once processed, what you see is NOT RAW, it is something else....either JPEG, TIFF or whatever protocol you "save" it as), then you are looking at a thumbnail, a small preview image.
If you try to view a RAW file directly, all you'll "see" on your screen is a streaky, reddish-brown smear. RAW files are just that, it is a file of all the data the sensor collected while the shutter was open. That's why its so large, and its also why you can adjust white balance, shutter speed and many other parameters in a RAW file, that you can't adjust once the image is saved in JPEG or TIFF. RAW files give you much more latitude to manipulate the image information, post shutter click. Sort of like a negative....but you just can't SEE an image in the RAW data. The camera creates a thumbnail for viewing purposes, and so does manipulating software such as PhotoShop.
If you actually mount the card on your desktop, and look in the directory you can, (at least, I can), see the thumbnail files in the directory along with the RAW files.
There are several articles in various magazines which discuss the RAW file structure, and the whys and wherefores why it is an option in the better cameras.
Hope this helps.

Right. the camera manufactures a small preview image of the picture you take and save as RAW. Look at your Flash Card contents. You'll see them. The thumbnail is the image you see in your little LCD screen right after pushing the shutter button.
Er.. I don't see them - and I download my raw files suffixed with the NEF format knowing what they are because they ARE called NEF files or if I shoot Jpeg or Tiffs - that is what I download..
.. don't have any thumbnails!
are you on PC?
