The viewer would of course display the same message. I even tried to test it using another method: Opened the JPG with notepad, I cut ONE known character from a location easy to remember (like the first character of the 2nd line) then save the file. When I tried to open, Windows would say "Windows Photo Viewer can't open this picture because the file appears to be damaged, corrupted, or is too large". All of them (the original JPG, the converted TXT file and the newly created TXT file) are of the exact same size, to bytes. I pasted the copied text to another blank TXT file and saved it as JPG, I compared the new file size with the original JPG.I disabled wrapping and selected all the text using Ctrl+A (to make sure nothing's missed).It should look like this, oddly looking sequences of texts, and some of them (very rare) are actually meaningful, like in the screenshot below "creator: dg-jpeg v1.0." I changed a picture (JPG) file to TXT by simply changing its extension (or one could just choose to open the JPG with notepad, same thing).Here is the detailed experiment, my OS is Windows 7 圆4 SP1: This phenomenon has been leaving me questions to ask.
