It is an .ico file which can, and usually do, have several different size images emebdded in one file. Based on what your view setting is will detemine which pic you see. Try it with several folders. Many pics are the came, but some are different.

Example, when I make an icon in Paint.NET and save as icon, I have a choice of about 12 sizes and and bit formats to save it in.

After scrutinizing your file, I found out that this is actually a .JFIF file-- it is ".. a format for exchanging JPEG encoded files compliant with the JPEG Interchange Format (JIF) standard."

What this means for practicality is that you can embed thumbnails.

After further scrutiny, I managed to extract the thumbnail and I posted it here for curiosity's sake.

For even more curiosity's sake, the thumbnail in this file's metadata starts at address 0x134 (Byte 308) and ends at 0x1C34 (byte 7220).
