I would assume that the content of these SWF files is video, is that correct? Do you have a MAC or Windows PC?
If you are on a MAC then there's probably no way you can play these SWF files to view the content. However, PCs on earlier versions of MS Windows prior to about 2020 (e.g. Windows XP or Windows 2000) should still be able to launch the SWF by double-clicking the file, unless the Samsung device has also added some other form of protection (e.g. password or encryption).
So, if you can find a PC capable of launching the SWF, one possible way you might be able to recover the footage is to use another capture program on that PC (e.g. Captivate or Snagit) to capture the video as it plays.
The SWF format can package other types of content, including images, sound and video. If any of these SWF converters are at least able to open the SWF package to show the files it contains, you might simply be able to extract the videos that way. But since SWF was officially 'dead' from about 2020 onward, there are not going to be too many apps out there designed to work with it.
