>> Anon 104372 So, I did an experiment. I opened Unyl_is_love.swf in SA Flash Player and did "Create Project", thus getting an .exe file (player + flash). Then, I used the "exe2swf" program to extract the .swf file from this .exe, but I got a different swf than I had originally. The file size was different: Original flash Unyl_is_love.swf: 364 KB (373,322 bytes) After conversion swf -> exe -> swf: 367 KB (376,002 bytes) Then I thought that the "exe2swf" program was not working correctly and used the Flash Convert 1.0 program (unregistered version), and then did the same: did Create Project, got an exe, and now using Flash Convert 1.0 I extracted the swf from the exe again. And again I got a file of 367 KB (376,002 bytes), which is 2680 bytes different from the original file. Why is that? What software should I use to correctly extract swf from exe? And I have extracted so many flashes from exe..! I have had Flash Convert 1.0 since 2004... It turns out that for many years it has been extracting flashes incorrectly. Why I noticed this: flashes that I took from the DaniMult Web Archive sometimes survived in two versions - swf and exe. I found that the regular swf versions differed in size from swf extracted from exe. It is interesting that despite the different sizes, sometimes swfchan considered them the same (and VirusTotal - different), sometimes swfchan accepted them as new flashes. So what software should I use to correctly extract swf from exe? help.swf (9.5 KiB) 640x480, Compressed (Deflate). 80 frames, 12 fps (00:07). Ver8, AS1/AS2. Network access: Text: Yes. Bitmaps: Audio: Video: [find in archive]
>> Anon 104374 I've only used "Sothink EXE to SWF Extractor", but that was many years ago. https://www.sothink.com/product/flashdec ompiler/help/extractor.htm It's part of "Sothink SWF Decompiler" which wasn't free back in the day, I don't know if it has been made free or not but it doesn't seem like it. They can't have that many customers these days. I searched and found that you can download it from Internet Archive: https://archive.org/details/sothink-swf- decompiler-74 Look on the right side for a blue ZIP link. The main decompiler program seems to be a trial version but included is also EXE2SWFExtractor.exe inside the Tools folder, which maybe isn't a trial version? I've not checked but if you want to you can try extracting the .swf file with that program.
>> Anon 104375 It has been experimentally shown that, it seems, Flashes of version 6 do not change the file size when converting swf -> exe -> swf, while versions 7 and 8 do change the file size. But if take a swollen flashy and convert swf -> exe -> swf again, the file size does not change anymore, it remains swollen, but the same. >># Thank you!
>> Anon 104398 Did you check compression? The converter switching to a different algorithm would be my first and only guess.
>> Anon 104477 I've just found two versions of humor_pong.swf. One is 156678 bytes and was downloaded from /f/, the other is 157598 bytes and was downloaded from this site's /show/. The difference is 920 bytes. The swfchan archive, when I search by filesize, resolves both to flash #7440 and serves the 156678 byte version. ffdec says both are 156678 bytes. It turned out that the larger flash had some trailing data with a JFIF magic number. I copied that to a new file, opened it in an image viewer and it was a 87x60 image with a crusty 13x13 Flash logo in the middle over a black background. Could the extractor have kept the executable's icon?
