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 EQ data, and CAD-oriented versions exist but are comparatively rare.
Because `.AEC` files are commonly metadata-style helpers, inspecting neighboring files can immediately provide context—`.aep`, `.c4d`, and render outputs like `.png`/`.exr` imply a C4D/After Effects environment, while large numbers of `.wav`/`.mp3` and preset directories suggest audio; file Properties can confirm size and timing, with tiny `.AEC` files often signaling interchange or preset descriptors, and viewing the file in a text editor may reveal comp/camera/layer strings or audio terms like EQ, threshold, or reverb, though binary output is also possible, but the most definitive test is simply opening it in the likeliest parent program, since Windows associations are not always trustworthy.
Opening an `.AEC` file comes down to identifying its creator software, because Windows associations may mislead and `.aec` isn’t designed to open like regular media; in Cinema 4D→After Effects workflows, `.aec` files are imported into AE to reconstruct cameras, nulls, and layer layout, so verify the C4D→AE importer is installed and then use AE’s File → Import, and if AE refuses it, it may not be that type of `.aec`, the importer may be absent, or version mismatches may exist, making the next logical move to confirm its context—often obvious if it’s beside `.c4d` or render sequences—and update/install the proper importer.
If the `.AEC` file comes from audio-effect workflows, indicated by folder items like “preset,” “effects,” or “chain” and numerous `.wav`/`.mp3` files, it should be treated as an effect-chain/preset file that the audio editor loads internally—Acoustica tools provide a Load/Apply Effect Chain option for this—restoring saved processing settings; before proceeding, check Properties for context clues and peek at it in Notepad for layer/comp/scene versus EQ/release/attack, and once you identify the originating program, always open it from inside that software via Load/Import, not by double-clicking, which relies on potentially incorrect Windows associations.

That’s why an `.AEC` file may act as a Cinema 4D scene handoff in one pipeline, while functioning as an audio effect-chain preset in another, or as something proprietary in yet another; this means you cannot trust the extension alone—context, project origin, nearby assets, file size, or a text-editor scan for keywords are needed to tell which variant it is, and then you open it strictly through the correct originating application.
