Developer tools

For developers: Flash developers often work on SWF or FLV content that is eventually deployed on the Internet. During development of these applications, developers need to test while the SWF or FLV content is stored locally rather than deployed on a web server. For security, Flash Player blocks SWF and FLV content stored locally from accessing the Internet, and it prevents SWF and FLV content on the Internet from accessing your computer.

Accordingly, during local testing, Flash Player can show security warnings that prevent the application from functioning as intended. You can resolve this issue by using the Trusted Location Settings panel to designate your own SWF or FLV content as trusted. You can designate paths to individual files as trusted, or designate folders as trusted. All files in a trusted folder and any of its subfolders are trusted as well.
