How do I find the largest files on my iPhone?

Go to Settings → General → iPhone Storage. The list ranks apps by total size automatically. Tap any app to see a breakdown of app size vs. Documents & Data — that second number is where large hidden files usually live.

What takes up the most storage on an iPhone?

Videos are almost always the biggest culprits, especially 4K footage and screen recordings. After that, offline downloads from streaming apps, iMessage video attachments, and large files in the Files app are the most common offenders.

Can I delete large files without losing anything important?

Yes, if you back up first. For videos, make sure they're saved to iCloud, Google Photos, or your computer before deleting from the iPhone. App downloads and message attachments are generally safe to delete without backup.

Why hasn't my storage changed after deleting large files?

Deleted photos and videos go to the Recently Deleted album in Photos, where they sit for 30 days. Open Photos → Albums → Recently Deleted and tap Delete All to free the space immediately.

Does EverClean AI delete files automatically?

No. EverClean AI shows you what it finds — duplicate videos, large media, similar files — and you choose what to delete. Nothing is removed without your review and approval.

How often should I check for large files on my iPhone?

Once a month is usually enough. A quick check of Settings → iPhone Storage to look for apps with inflated Documents & Data numbers keeps things from spiraling.
