Soufflé is a free OS X application that will automatically create thumbnails for all SWF files on your Mac.
No need to open them to see what’s inside - just click the file and Soufflé will show you preview thumbnail. You can even choose the movie moment for creating the preview.
Soufflé provides you with all information about SWF file you are previewing: it will show you its dimensions, duration, Flash version, frames per second, etc. Just click any SWF file and you will see this information along with the preview.
NOTE: Soufflé can only be purchased via the Mac App Store (the buy link redirects you to its App Store page). To purchase/download applications via the App Store an Apple account is required.
