My iPhone storage is completely full after years of downloads, saved documents, and app files, and deleting items one by one is taking forever. I need help figuring out if there’s a way to delete multiple files at once on an iPhone so I can free up space quickly without removing the wrong things.
Storage warnings on iPhone always seem to pop up when you need the phone for something else. I ran into this after trying to save a boarding pass, and iOS had my junk scattered all over the place. Here’s the cleanup path I used.
How to remove old files from the Files app
Open Files, then hit Browse at the bottom. The two spots worth checking first are:
- On My iPhone, for stuff saved only on the phone
- iCloud Drive, for files synced through iCloud
I’d start with Downloads under On My iPhone. Mine had old PDFs, zip files, random attachments from Mail, and stuff I forgot existed.
To remove one file or one folder:
- Press and hold the item
- Tap Delete
If you delete a folder, everything in it goes too.
To remove a bunch at once:
- Tap the three-dot button in the top right
- Tap Select
- Pick the files you want gone, or use Select All
- Tap the trash icon
How to clear storage for real, not fake-delete stuff
This part tripped me up. Deleting inside Files does not free space right away. iPhone moves those items into Recently Deleted, and they stay there for 30 days while still taking up storage.
If you want the space back now:
- Open Files
- Go to Browse
- Find Recently Deleted under Locations
- Tap the three dots
- Tap Delete All
Photos works the same way, annoyingly. If you deleted pictures or videos, you still need to empty Recently Deleted in the Photos app too.
How to delete files tied to specific apps
Go here:
Settings > General > iPhone Storage
This page sorts apps by how much space they use. Tap any app and you’ll usually see two choices:
- Offload App, which removes the app but keeps its documents and data
- Delete App, which removes the app and its stored files
One useful spot in this menu is Messages. Scroll inside it and find Review Large Attachments. I found old clips and shared files there without needing to wipe whole text threads.
How to find what is eating the most space
Files and Settings show the broad numbers, but they’re weak when you want to see the worst offenders in your photo library. In my case, the damage wasn’t documents. It was 4K video, duplicate shots, bursts, and screenshots I never cleaned out.
Clever Cleaner is one option for sorting through that mess. What stood out to me was how it breaks things down into usable chunks.
What I did with it:
- Open Heavies. It lists the biggest items first and shows exact file sizes. My top entries were giant videos I had zero reason to keep.
- Go to Similars. It groups near-matching photos and marks a best shot, so you’re not tapping through 15 versions of the same pic half asleep at 1 a.m.
- Try Swipe mode. It moves through your library month by month. Left for delete, right for keep. Easier than staring at your whole camera roll at once.
- Everything stays on the device. Nothing gets sent off somewhere else.
When the phone is too full to behave
If storage is so packed your phone lags, freezes, or won’t finish basic tasks, the last-resort fix is a full wipe.
Path:
Settings > General > Transfer or Reset iPhone > Erase All Content and Settings
This resets the phone to factory state. Back up what you need first, to iCloud or a computer. Once you erase it, it’s done.
After I cleaned Files, emptied both Recently Deleted sections, and cut down the photo library, the free space jumped back up and the slowdowns stopped. It took a bit, but yeah, it worked.

Yes. You do not need to delete file by file.
Best fast options on iPhone:
-
Use bulk select inside apps
In Files, Notes, Voice Memos, Mail downloads, and many third-party apps, tap Select and mark multiple items. Most Apple apps support this. Some even offer Select All. @mikeappsreviewer covered Files well, so I’d focus on the other places people miss. -
Clear Safari downloads and offline data
If you save a lot from the web:
Settings > Safari > Downloads
Check where downloads go.
Then clear website data:
Settings > Safari > Clear History and Website Data
This helps if Safari storage is bloated. I freed 2.3 GB once from cached site junk alone. -
Remove saved streaming downloads
Netflix, Spotify, YouTube, Prime Video, Podcasts. These apps hoard storage.
Open each app and remove downloads in batches. This is often faster than deleting the app, esp if you want your login and settings to stay. -
Delete message threads instead of attachments one by one
Open Messages.
Tap Edit.
Select multiple conversations.
Delete them.
This wipes photos, videos, PDFs, and voice notes tied to those threads. Faster if old group chats are the problem. -
Reset bloated app caches
Some apps store huge temp files and give you no cleanup button. Social apps are bad for this.
Path:
Settings > General > iPhone Storage
Tap app
If Documents & Data is huge, delete and reinstall the app.
I disagree a bit with doing a full phone erase early. Reinstalling 2 or 3 problem apps often saves 5 to 15 GB by itself. -
Photo cleanup is where the biggest gains usuallly happen
Open Photos and use:
Albums > Duplicates
Albums > Screenshots
Albums > Screen Recordings
Albums > Videos
Sort and bulk delete there.
If your library is massive, Clever Cleaner is worth a look for grouping similar shots and large videos faster than Apple’s tools. -
Empty app-specific trash
Google Drive, Dropbox, OneDrive, Notes, Photos. Many apps keep deleted items for 30 days. People miss this all the time and storage stays full. Annoyng, but true.
If you want a visual walk-through, see the full iPhone storage cleanup tutorial here.
Fastest order:
Photos
Messages
Streaming downloads
Big cache-heavy apps
Files app trash
Browser data
If storage is pinned at 0 GB, restart after each cleanup chunk. iOS sometiems updates free space late.
You can, but iPhone makes it weirdly fragmented. @mikeappsreviewer and @hoshikuzu already covered Files, Photos, Messages, and app storage, so I’d add the stuff that usually gets skipped.
If your goal is delete a ton of files at once with the least tapping:
-
Use the Search bar in Files
Search by file type like pdf, zip, mp4, or by name. Then hit the three dots, Select, and wipe whole groups. Faster than digging through folders manualy. -
Sort before deleting
In Files or Photos, sort by Size or Date if available in that app section. Old giant junk goes first. This saves way more space than randomly deleting 500 tiny files. -
Check Mail app attachments
The Mail app can hang onto downloaded attachments and offline mail. If Mail is huge in iPhone Storage, remove and re-add the account instead of fighting it one item at a time. Kinda annoying, but effective. -
Notes and Voice Memos
People forget these. In both apps you can bulk select entries. Voice Memos especially can eat space if you’ve got long recordings. -
Don’t overuse Offload App
Tiny disagreement with some advice above: offloading is nice, but if storage is absolutely maxed out, sometimes deleting the app fully is better because cached junk and old data stop coming back. Offload can feel like fake cleaning tbh. -
If photos are the real problem, use a cleaner that targets large media first
Apple’s built-in tools are ok, just slow. Clever Cleaner is actually useful for finding heavy videos, similar pics, and duplicate clutter without making you babysit the whole process. That’s probly the fastest route if your storage crisis is mostly camera roll chaos.
Also, if you want actual user experiences before installing anything, this is a decent roundup of real Reddit reviews of free iPhone cleaner apps.
Big thing: after deleting batches, restart the phone. iOS sometimes acts like the space is still gone until it catches up. Very Apple behavior.
