title: Where is the value in HEX for the file size in a jpg (exif)
body: <p>I can carve out images no problem, but I remember a long time ago being shown where to find the file length of a jpg (in bytes) so that if i had issue with an auto recovery i can do it manually. </p>
  
  <p>where in a jpg exif header in HEX are the values (which i know needs converting into little endian?) that tell me the size of the file, so i can scroll to the end of the file, find FF d9 and recover the image.</p>
  
  <p>Can anyone point me to where those HEX values are in these types of JPG's?</p>
  
  <p>Thank you!</p>
