VN and VLLO keep three things on your iPhone: active project data, a working cache of trimmed clips and previews, and any exports you saved. The safe way to free space is to delete finished projects and clear exports you've already saved, not to randomly wipe folders. Start by checking Settings > General > iPhone Storage and tapping VN or VLLO to see each app's footprint.

TL;DR

  • Both editors store imported clips and render previews, so projects grow far larger than the source video.
  • Delete completed projects inside the app once you've exported the final video.
  • Exports save to Photos by default and double your storage use until you remove either copy.
  • iOS "Offload App" keeps your projects; only deleting projects or the app reclaims project space.
  • There's no in-app "clear cache" button, so back up before deleting anything.

How do I see what VN or VLLO is using?

Open Settings > General > iPhone Storage, scroll to VN or VLLO, and look at the "Documents & Data" figure. That number includes your projects, imported media copies, and cached previews. The app's own download size is small; the documents are what balloon.

How do I clear VN's storage without losing active work?

VN copies your imported clips into each project, so old projects hold full media even after you've deleted the originals from Photos. In VN's project list, swipe or long-press a finished project and choose Delete. Before deleting, open the project, tap Export, and save the final video. VN has no separate cache toggle, deleting the project is how you clear its working files.

How do I clear VLLO's storage safely?

VLLO behaves the same way: each project stores its own copy of imported media plus render data. On the main screen, tap the project, then use the menu to Delete projects you've already exported. There is no standalone cache-clear in VLLO, so removing finished projects is the reliable path to reclaim space.

Where do my exports go, and how do I clear them?

Both apps export finished videos to your Photos library by default. That means a 2 GB project can leave a 2 GB export sitting in Photos on top of the project itself. Open Photos, find the exported clips (check Recents or a VN/VLLO-named album), and delete the ones you've already backed up. Then empty Photos > Albums > Recently Deleted.

What iOS does natively, and where it stops

iOS gives you Offload App under Settings > General > iPhone Storage > VN/VLLO. This removes the app binary but preserves every project and cached file, so it reclaims almost nothing for a project-heavy editor. iOS cannot selectively purge a single app's cache the way Android can; it only offers offload or full delete. To actually free project storage, you must delete projects in-app or delete the app entirely.

What this cannot do

Clearing cache is not the same as deleting your projects, and in VN and VLLO there is no disposable cache to clear, the "cache" is bound to your editable projects. Deleting a project is permanent and removes your editable timeline forever. Always export the final video and confirm it saved before you delete anything. If your storage problem is wider than these two apps, the same principles apply to other editors, see how to clear CapCut cache and free huge space.

FAQ

Does deleting a VN or VLLO project delete my exported video?

No. Once you've exported to Photos, the video lives in your Photos library independently. Deleting the project removes only the editable timeline and its imported media copies, not the finished export.

Can I clear VN/VLLO cache without deleting projects?

Not directly. Neither app exposes a cache-only button on iPhone. The cached previews and clips are tied to each project, so the only way to reclaim that space is to delete the projects you no longer need.

Why is VLLO using more space than my original videos?

Because VLLO copies imported media into the project and adds render/preview data on top. A project can be larger than the source footage. Deleting finished projects after export brings that space back.
