I’ve just came to notice that Google is actually indexing swf files,that is, it is parsing the text found within the file, It seems that this feature has been around for a while now, Think of all the wonderful things you can do with that, like fetching flashy illustrations for a hard to “visualize” subject like DNA synthesis through Google.
Maybe Google is not going “deep” within the file but I think the current “depth” is quite sufficient.
You might find these queries interesting
Astigmatism filetype:swf
Loop of henle filetype:swf
علي فكرة يا مصطفي أنا واخد بالي من الحكاية ديه من حوالي شهرين ولكن للاسف نسيت اقولك يعني كده ملف ال swf اصبح مثل ال pdf بالنسبة لمحرك البحث جوجل وهذه صورة كمثل لهذه الخاصية
