Swifty Compress & Swifty Decompress 1.1

SWFcomp and SWFdecomp are copyrighted freeware utility applications to
compress and decompress SWF files.

(Both of the utilities will work for SWF version 5 and below files [without a warning] although this is against the official specs. You can play any compressed SWF with version 6 of the Flash player).

You should supply the SWF filename as commandline parameter.
The easiest way to do this is dragging and dropping a SWF file over the exe files.
