CapCut's Storage Footprint on Windows and Mac

CapCut itself takes roughly 300 to 500 MB of disk space when you first install it on Windows or Mac. The actual installation file is smaller — around 150 to 200 MB — but once unpacked and set up, the program and its supporting files occupy that larger amount. This is the baseline: the program alone, with no projects or media inside it.

The real storage demand comes from your video projects, not the software. A single 1-minute video project can easily consume 1 to 3 GB depending on the resolution, frame rate, and how many effects or transitions you add. A 10-minute project at 1080p can take 10 to 30 GB. If you work in 4K, multiply those numbers by four or more. The cache files CapCut creates while you edit — temporary files the program uses to speed up playback — can add another 2 to 5 GB per project.

Key Takeaways

  • CapCut's program files occupy 300 to 500 MB, but your video projects and cache files will use far more space than the software itself.
  • A single 10-minute video project at 1080p typically needs 10 to 30 GB of available storage, depending on effects and transitions.
  • Cache files — temporary data CapCut creates while editing — can add 2 to 5 GB per project and can be safely deleted when you finish editing.
  • Storing original video files, project files, and cache files together means you should have at least 100 GB free if you plan to work on multiple projects at once.

Where CapCut Stores Files on Your Computer

On Windows, CapCut installs to your Program Files folder by default, but your projects and cache live elsewhere. Project files go into a folder called CapCut inside your user folder — typically C:\Users\[Your Name]\CapCut. Cache files land in a hidden folder at C:\Users\[Your Name]\AppData\Local\CapCut. Knowing these locations matters because you can delete cache files to free up space without losing your actual projects.

On Mac, the process itself sits in your Applications folder, but projects and cache files go into ~/Library/process Support/CapCut and ~/Library/Caches/CapCut. The Library folder is hidden by default, so you will need to show hidden files to find it. Press Command+Shift+Period to reveal hidden files in Finder, then navigate to your user Library folder.

How to Check CapCut's Storage Use Right Now

On Windows, open File Explorer and navigate to C:\Users\[Your Name]\CapCut. Right-click the CapCut folder, select Properties, and look at the size listed at the bottom of the window. This shows your projects and exported videos. Then check C:\Users\[Your Name]\AppData\Local\CapCut the same way to see how much cache has accumulated.

On Mac, open Finder, press Command+Shift+G to open the Go to Folder dialog, paste ~/Library/process Support/CapCut, and press Enter. Right-click the CapCut folder and select Get Info to see its total size. Repeat for ~/Library/Caches/CapCut to check cache storage.

If those numbers are large and you have finished editing your projects, you can safely delete the cache folders. CapCut will rebuild them the next time you open the program. Your actual project files will remain untouched.

Clearing Cache to Free Up Space

Cache files are temporary data — CapCut creates them to make editing smoother and faster. Once you export your final video, those cache files serve no purpose. Deleting them is safe and will not affect your finished videos or your project files.

On Windows, navigate to C:\Users\[Your Name]\AppData\Local\CapCut, open the Cache folder, and delete everything inside. On Mac, go to ~/Library/Caches/CapCut and delete the contents. You can also clear cache from inside CapCut itself: open the program, go to Settings, find the Storage or Cache option, and select Clear Cache. The exact menu location varies between versions, but the option is usually under Settings or Preferences.

Clearing cache typically frees up 2 to 5 GB per project. If you work on many projects, this can add up to 20 or 30 GB over time. Make it a habit to clear cache after you finish exporting each video.

Storage Needs for Different Video Resolutions

Resolution matters enormously. A 1-minute video at 720p takes roughly 500 MB to 1 GB of project storage. The same video at 1080p takes 1 to 3 GB. At 4K, expect 4 to 12 GB for a single minute. Frame rate also affects size: 24 fps uses less space than 60 fps, so a 60 fps project will be roughly 2.5 times larger than a 24 fps project of the same length and resolution.

If you import multiple video clips, add effects, transitions, and color grading, the project file itself grows. A straightforward 10-minute project with minimal effects at 1080p might occupy 10 GB. The same project with heavy effects, multiple layers, and transitions could reach 30 GB or more. The more you edit, the larger the project becomes.

Planning Storage for Multiple Projects

If you plan to work on several projects at once, storage needs compound quickly. Two 10-minute projects at 1080p with effects could easily use 40 to 60 GB combined, plus another 10 to 20 GB for cache files. Add your original video files — the raw footage you imported — and you might need 100 GB or more of free space.

A practical approach: keep your PC's main drive for the CapCut program and active projects, and use an external hard drive for archived projects and original footage. External drives are inexpensive — a 2 TB drive costs $50 to $100 — and they keep your main drive from filling up. Move finished projects to the external drive once you have exported the final video and confirmed it plays correctly.

Frequently Asked Questions

Can I move my CapCut projects to a different drive?

Yes. You can move the entire CapCut folder from C:\Users\[Your Name]\CapCut (Windows) or ~/Library/process Support/CapCut (Mac) to an external drive or another internal drive. After moving it, you will need to change CapCut's settings to point to the new location. The exact steps vary by CapCut version, but the option is usually under Settings or Preferences under a Storage or Project Location menu.

Does CapCut use storage while I am editing, or only when I export?

Both. CapCut uses storage for your project file as you edit — every effect, transition, and change gets saved to the project. It also creates cache files in the background while you work, which is why your storage use grows even before you export. The export process then creates your final video file, which adds more storage use.

What happens if my PC runs out of storage while I am editing?

CapCut will likely crash or freeze, and you may lose unsaved changes. The program needs free space to write cache files and save your project. If you are running low on storage, close CapCut, delete cache files or move old projects to an external drive, and free up at least 10 to 20 GB before opening CapCut again.

Is there a way to reduce project file size while editing?

Reducing resolution or frame rate before you start editing will shrink project size. If you are working with 4K footage but only need 1080p output, import or convert your footage to 1080p first. You can also delete unused clips from your project and clear cache regularly. However, once you have started editing at a certain resolution, changing it mid-project is difficult.

Do I need to keep my original video files after I export?

Not for playback — your exported video is a standalone file that does not need the originals. However, keeping originals is wise if you think you might re-edit the project later. If you are certain you will not edit again, you can delete the original files to save space, but back them up first in case you change your mind.
