Why and When to Clear CapCut Cache

Clearing your CapCut cache removes temporary files the app creates while you edit videos. These files pile up over time and can slow down your computer, cause the app to freeze, or prevent new projects from loading properly. If CapCut is running sluggish, crashing when you open it, or taking forever to render, a cache clear often fixes the problem without deleting any of your actual projects.

You should clear cache when CapCut starts behaving oddly, before working on a large project, or roughly once a month if you edit regularly. The process takes two minutes and won't affect your saved videos or project files—only the temporary working data.

Key Takeaways

  • CapCut stores temporary files in a hidden folder on your Windows drive that you can safely delete without losing your projects.
  • The fastest method is to go to Settings > Storage > Cache in CapCut itself and tap the clear button.
  • If CapCut won't open, you can manually delete the cache folder by navigating to AppData on your C: drive.
  • Clearing cache takes about two minutes and often fixes freezing, slow performance, or loading errors.
  • Your saved projects and exported videos remain untouched when you clear cache.

Clear Cache Through CapCut Settings (Easiest Method)

Open CapCut on your Windows PC. Click the three horizontal lines (hamburger menu) in the top left corner, then select Settings. Look for the Storage or Cache option—the exact wording depends on your CapCut version, but it will be labeled clearly.

Once you find it, you'll see a button that says Clear Cache or Delete Cache. Click it. A confirmation window may appear asking if you're sure—click yes. The app will process for a few seconds, then show a message confirming the cache was cleared. Close Settings and restart CapCut. The app should run noticeably faster.

Manually Delete Cache if CapCut Won't Open

If CapCut crashes on startup or won't open at all, you can't use the Settings method. Instead, you'll delete the cache folder directly through Windows File Explorer. Open File Explorer and look at the address bar at the top. Type or paste this path exactly: C:\Users\YourUsername\AppData\Local\BytedanceSDK. Replace "YourUsername" with your actual Windows username.

Press Enter. You should see a folder called CapCut or CapCutSDK. Open it. Inside, look for a folder named Cache or cache. Right-click it and select Delete. If you see a folder called Temp, delete that too—it contains the same kind of temporary files. Empty your Windows Recycle Bin afterward to free up the space.

Now try opening CapCut again. It will rebuild the cache folder automatically the next time you use it.

Finding the AppData Folder if It's Hidden

The AppData folder is hidden by default on Windows, so you might not see it when you navigate to C:\Users\YourUsername. If that happens, you need to show hidden files. In File Explorer, click the View tab at the top. Look for a checkbox labeled Hidden Items and check it. Now AppData will appear in your user folder.

Alternatively, you can skip the folder navigation entirely. Open File Explorer, click the address bar, and type the full path C:\Users\YourUsername\AppData\Local\BytedanceSDK directly. Windows will take you straight there without needing to show hidden files.

What Happens After You Clear Cache

After clearing cache, CapCut will run faster because it no longer has to sort through old temporary files. The first time you open a project after clearing, the app may take a few extra seconds to rebuild its working files—this is normal and only happens once. Your projects, timelines, and exported videos are completely safe; clearing cache only removes the temporary data CapCut uses while you're actively editing.

If you were experiencing crashes or freezing, you should notice improvement when ready. If problems continue, the issue may be something else—like insufficient disk space or a corrupted project file—rather than cache buildup.

How Often to Clear Cache

If you edit videos regularly, clear cache once a month as routine maintenance. If you only use CapCut occasionally, you can clear it whenever you notice the app slowing down. There's no harm in clearing cache frequently—it's a safe operation that only removes temporary files. Some editors clear cache before starting a big project just to may support the app has a clean slate and maximum performance.

If you find yourself clearing cache more than once a week to fix crashes, something else may be wrong. Check that you have at least 5 to 10 GB of free space on your C: drive, and consider reinstalling CapCut if problems persist.

Frequently Asked Questions

Will clearing cache delete my projects or videos?

No. Cache contains only temporary working files. Your saved projects, timelines, and any videos you've exported remain untouched. You can clear cache without any risk to your work.

What if I don't see a Cache folder in AppData?

It may have a slightly different name depending on your CapCut version—look for folders named Temp, Temporary, or anything with "cache" in the name. If you see nothing that looks like cache, use the Settings method instead, which is simpler and works for all versions.

How much space does CapCut cache usually take up?

Cache typically ranges from 100 MB to 2 GB depending on how many projects you've worked on. Clearing it won't free up massive amounts of space, but it does help performance more than it helps storage.

Should I clear cache before or after exporting a video?

It doesn't matter. Clear cache whenever you notice slowness. Clearing before export won't speed up the export itself, but clearing after export removes the temporary files from that project and can help the app run faster overall.

What if CapCut still crashes after clearing cache?

Try restarting your computer, then reinstalling CapCut. If crashes continue, check that Windows is up to date and that you have enough free disk space. You can also try importing your project into a new CapCut project file in case the original file became corrupted.
