An SWF file (Small Web Format) is a container for playing back FLV (Flash Video) files—a popular type of streaming video on sites like YouTube. These files are recognized by VLC Media Player and can be opened just like any other file supported by VLC. If you cannot open an SWF, try downloading the latest version of the program, in case your current version is corrupt.
