After Effects projects link to external assets, such as footage, images, and audio, by file path, not by embedding them into the .aep file. Move the project to a different folder or computer without those linked files, and the timeline fills with color bars and “missing footage” warnings. Collect Files solves this by packaging everything into one portable folder.
The collection itself takes about 30 seconds. But the steps before and after collecting determine whether the handoff actually works or whether the recipient opens your project to a wall of missing file warnings.

Collect Files is a dependency management function in After Effects (File → Dependencies → Collect Files) that copies every external asset your project references, including footage, audio, images, and the .aep file itself, into a single self-contained folder.
The output is straightforward: After Effects creates a new folder containing your .aep project file, a (Footage) subfolder with all linked media, and a Report.txt that lists every file, effect, font, and plugin the project uses. This folder can be moved to an external drive, uploaded to cloud storage, or sent to another editor without breaking any file links.
You need to collect files when transferring a project to a different computer, handing off to another editor or client, archiving completed work, or submitting to a render farm. If your project uses only native shape layers, solids, and text with no imported media, the .aep alone is enough, no collection needed.
Running Collect Files on a messy project creates a messy package. Unused footage, duplicate imports, and unnamed compositions all get swept into the collected folder, inflating file size and making the project harder for anyone else to navigate.
Run through this cleanup sequence before collecting:
1. Remove Unused Footage. Go to File → Dependencies → Remove Unused Footage. This deletes every asset in your Project Panel that isn’t used in any composition. Projects that accumulated test clips, alternate versions, and placeholder images over weeks of editing shrink significantly after this step.
2. Consolidate All Footage. Go to File → Dependencies → Consolidate All Footage. If you imported the same file multiple times, this merges duplicate entries into a single reference. Fewer source files mean a smaller collected folder and fewer linking issues.
3. Rename Layers and Delete Old Comps. If your timeline is full of “Shape Layer 14” and “Comp 3 Copy Copy,” now is the time to fix it. Rename layers to reflect their function (e.g., “Logo_Scale_In,” “BG_Gradient”). Delete test compositions and old versions you’re not using. This doesn’t affect file size much, but it makes the project usable for whoever opens it next.
4. Save the Project Press Ctrl+S (Cmd+S on Mac). After Effects won’t let you collect an unsaved project. Save first, then collect.
This cleanup takes five minutes and prevents the collected folder from being twice as large as it needs to be, packed with assets nobody will use.
Once your project is cleaned up and saved, the collection itself is fast. Here’s the exact process with every setting explained:
Step 1: Go to File → Dependencies → Collect Files.
Step 2: In the dialog box, locate the Collect Source Files dropdown. This is the setting most editors skip past and the one that matters most. There are four options:
Step 3: Check the Reduce Project box. This strips unused footage and compositions from the collected .aep copy, so the recipient gets a clean file without leftover clutter. The original project on your machine stays untouched.
Step 4: Leave Generate Report Only unchecked. If this is checked, After Effects creates the Report.txt but doesn’t actually copy any files a common mistake that results in sending an empty folder.
Step 5: Click Collect, then name the folder clearly, something like ProjectName_Handoff_2026-02-20, so the recipient knows what they’re opening.
Step 6: Zip the entire folder before transferring. Zipping prevents files from separating during upload and keeps the folder structure intact.
After Effects places the collected .aep project file and a (Footage) subfolder inside your new folder. The .aep points to assets inside that (Footage) folder using relative paths, which is why both must stay together.
Collect Files gathers footage, images, and audio. But it skips two categories that break projects on the receiving end more often than missing footage does.
Fonts
After Effects does not package font files (.ttf or .otf) into the collected folder. If the recipient doesn’t have your fonts installed on their system, every text layer reverts to a default typeface, changing the look of the entire project. The fix: manually copy your font files into a “Fonts” subfolder inside the collected folder. Check Report.txt for the full list of fonts the project uses.
Plugins
Third-party plugins like Trapcode Particular, Element 3D, and Optical Flares are not included. If the recipient doesn’t own them, those effects render as missing or invisible. There’s no way to package plugins; they require separate licenses.
The fix: create a README.txt file in the collected folder listing the After Effects version you used, all required plugins and their version numbers, the fonts needed, and which composition is the final render. This takes two minutes and saves hours of back-and-forth troubleshooting.
Proxy files are another edge case. If you used low-resolution proxies during editing, check the proxy settings in the Collect dialog. Make sure you’re sending the original full-resolution source files, not the proxies, unless the recipient specifically needs them for offline editing.
Missing footage after collecting is the most common problem editors run into, and it almost always comes down to one of four causes.
The .aep was moved out of the collected folder. After Effects links the collected project to its (Footage) subfolder using relative paths. Drag the .aep onto your desktop while leaving the footage folder behind, and every link breaks. The fix: always keep the .aep file in the same directory as the (Footage) folder. Never separate them.
The folder was renamed or restructured after collection. Renaming the (Footage) subfolder or moving files between directories inside the collected folder breaks the paths After Effects stored. Leave the folder structure exactly as After Effects created it.
Files were already missing before collecting. If your project had missing footage warnings before you ran Collect Files, those assets weren’t available to copy. After Effects can’t collect what it can’t find. Always resolve missing files in your original project first, then collect.
Permission issues on external or network drives. Files on locked network drives or external drives that disconnected during collection may not copy properly.
To find missing files in a collected project, open the .aep and type “missing” into the search bar at the top of the Project Panel. This filters to show only offline assets. Right-click any missing file → Replace Footage → File → navigate to the correct file inside the (Footage) folder. After Effects often auto-relinks other missing files in the same directory once you fix the first one.
A properly packaged After Effects project looks like this:
📁 ProjectName_Handoff_2026-02-20
📄 ProjectName.aep
📁 (Footage)
📁 Fonts
📄 README.txt
The .aep file sits at the root alongside the (Footage) folder that After Effects generated. You add a Fonts subfolder with the .ttf/.otf files your text layers need. The README.txt documents the AE version, plugin requirements, font list, and which comp to render.
When you download After Effects project files that were organized from the start, labeled layers, structured compositions, and all assets properly linked collection becomes a non-issue because the project was built for portability. Disorganized projects with common mistakes, such as unnamed layers and scattered source files, are the ones that cause headaches during collection.

Consolidate All Footage merges duplicate imports in the Project Panel so the same file isn't listed multiple times. Collect Files copies all referenced assets into a new folder for transfer. Running Consolidate before Collecting reduces duplicates, keeping your collected folder lean.
Yes. Select the composition in the Project Panel first, then go to File → Dependencies → Collect Files and choose "For Selected Comps" in the Source Files dropdown. After Effects collects only the assets used by the specific composition.
Run Collect Files with "For All Compositions" selected and Reduce Project checked. Zip the collected folder. Transfer via external drive, cloud storage, or file-sharing service. On the other machine, unzip and open the .aep file from inside the collected folder, not from another location.
The .aep was moved outside its collected folder, or the footage was already missing before collection. Open the original project, fix any missing file warnings first, then collect again. If files went missing after collection, use Replace Footage → File to relink them from inside the (Footage) folder.
Collect Files does not gather linked Premiere Pro sequences or other Dynamic Link connections. If your project uses Dynamic Link, export those compositions as intermediate renders and import the rendered files into After Effects before collecting.
