DuckDuckGoA .flashfx file is a portable export of a project, not the live project itself. When one will not open, the question is almost always where it came from — a Guest mode browser store that was cleared, or a newer release of the editor than the one you are opening it in.
If one or more of these match what you are seeing, you are on the right page.
Ordered from most to least likely. Work down the list — each cause is paired with what to do about it.
Guest mode saves to browser local storage. A cache wipe, the end of a private-browsing session or a browser reinstall deletes it permanently with no recovery path. Create a free account so projects are stored in the cloud, and export .flashfx backups of anything important.
Open it in the same environment that produced it. FlashFX is a browser application, so this usually means someone on a newer release exported it — ask them to re-export, or reload the editor to pick up the current version.
Linked assets are referenced, not stored in the file, so they do not travel with it. Re-link the missing assets from the Asset Library, and embed images before exporting a project that will be opened elsewhere.
Cloud project deletion is permanent and immediate — there is no trash or recovery mechanism. Restore from a .flashfx backup if you have one.
If none of the causes above match, contact support with the steps to reproduce the problem, your browser and version, and any message from the browser console. You can reach us at support@flashfx.app.
