An `.AEC` file isn’t bound to a single specification because extensions are simply names, so you have to look at the origin to know what it is: in motion graphics—especially C4D exporting to After Effects—it’s typically an interchange file with layout data like cameras, lights, timing, and nulls, while in audio editing it may function as an effect-chain preset storing compression settings, and CAD-oriented versions exist but are comparatively rare.
Because `.AEC` files usually appear as support descriptors, looking at the surrounding files can quickly expose their purpose—AE/C4D workflows typically include `.aep`, `.c4d`, and render frames like `.png`/`.exr`, whereas audio setups feature `.

Opening an `.AEC` file depends on pairing it with the intended software, since Windows might map the extension wrong and the file isn’t meant to open like a standard asset; in a Cinema 4D and After Effects setup, you import the `.aec` into AE to rebuild cameras, nulls, and layering so renders sync properly, which means ensuring the C4D→AE importer is present and then using File → Import in AE, and if AE won’t accept it, the file may not be the right variant, the importer might not be installed, or workflow mismatches might exist, so confirming its folder (especially near `.c4d` or render files) and updating the importer from Cinema 4D is the next step.
If the `.AEC` seems to belong to an audio-editing context—signaled by “effects,” “preset,” “chain,” and numerous audio files—it functions as an effect-chain/preset file that must be opened from within the audio editor itself, such as via Acoustica’s Load/Apply Effect Chain option, allowing the program to reconstruct the effect rack; to avoid unnecessary attempts, inspect file Properties and neighbors, then check its text content in Notepad for either comp/light/layer or EQ/attack/release, and once you know the proper application, open it there using the software’s Load/Import command instead of relying on Windows’ double-click behavior.
When I say **”.AEC isn’t a single universal format,”** I mean the `.aec` extension doesn’t imply a fixed internal format, and operating systems like Windows don’t check what’s inside a file—they only use the extension to decide what program to open—so two unrelated tools can output `.aec` files whose internal content varies completely.
That’s why an `.AEC` file might contain motion-graphics scene data in one workflow, but in a different environment it could just as easily be an audio effect chain or preset storing EQ, compression, or other processing values, or even a niche proprietary format; so you cannot determine its type from the extension alone—you must check context, nearby project assets, file size, or textual hints before loading it inside the correct application that authored that `.AEC`.
