Extracting Thumbnail from CS6 AI

[venubwal]

Hi,
I am using exif tool following command to extract below CS6 file(ai) ; but i am unable to open genereated image.
Remaining all cases exiftool generates Thumnail/PageImage properly. But I see issue is only with this file.
Please help me; why generating image with this file is an issue

exiftool.exe -xmp -b "newindd.indd" -w newindd.indd.txt
exiftool -b -ThumbnailImage newindd.indd > newindd.indd.jpg
exiftool -b -PageImage "newindd.indd" > newindd-pageinfo.jpg
exiftool -pageimage -b -listitem 1 newindd.indd > newindd.indd._2.jpg

Please also let me know what/how PageImage / Thumnail are difference.
Is there any single command to get Image either of these two depends upon its availability?
