How to Reduce OneDrive Documents and Data Storage on iPhone
Question details
The user needs to reduce the storage space consumed by OneDrive's Documents & Data on their iPhone.
- Product
- OneDrive for iOS
- Device & OS
- iOS
- Scenario
- Reclaiming iPhone local storage space that is unusually bogged down by the OneDrive app.
- Observed behavior
- OneDrive takes up substantial Documents & Data storage on the iPhone due to cached files, offline content, or data associated with another signed-in account, even when the Recycle Bin is fully empty.
Verify that all your recent document edits are fully synced to the cloud to prevent data loss before clearing the application cache or reinstalling the app.
Clear the OneDrive App Cache
Use the built-in troubleshooting tool to clear cached temporary files that inflate the app's storage footprint.
OneDrive caches files locally to improve performance when loading previews and documents. Over time, this cache can grow substantially. Clearing it is the quickest way to reclaim space without affecting your saved cloud data.
Open the OneDrive app on your iPhone and tap your profile icon located in the upper-left corner of the screen.
Tap on 'Settings' from the profile menu.
Scroll down and select 'Help & Feedback'.
Tap 'Clear Cache'. Once completed, check your iPhone storage settings again to see if the Documents & Data size has decreased.
Check Offline Files on Alternative Accounts
Identify and remove files marked for offline access on other signed-in accounts.
Reinstall the OneDrive App
Completely remove the app and its associated data from iOS, then reinstall it.
Manage Documents Efficiently with Less Storage Using WPS Office
If standalone Microsoft apps are taking up too much of your iPhone's local storage, consider switching to WPS Office. This all-in-one suite handles Word, Excel, PowerPoint, and PDF files seamlessly in a single, lightweight application.
- 1. Download the App: Search for WPS Office in the iOS App Store and install the lightweight application.
- 2. Connect Your Cloud Drives: Open WPS Office and easily link your OneDrive, Google Drive, or Dropbox accounts to directly edit files without taking up local space.
- 3. Edit Seamlessly: Open, edit, and save your documents with a familiar UI that fully supports native Microsoft Office formats.
Frequently Asked Questions
Why is OneDrive's Documents & Data so large on my iPhone?
This category inflates because the app stores cache files to load document previews faster, saves files you've marked for offline use, and occasionally holds onto fragmented data from previous sessions or alternative signed-in accounts.
Will clearing the OneDrive app cache delete my photos or documents?
No. Clearing the app cache through the Help & Feedback menu only removes temporary local viewing files. Your actual documents, photos, and files remain safely stored in the cloud.
How do I see exactly what is taking up space inside my OneDrive app?
Unfortunately, iOS clusters all of this under 'Documents & Data' in the iPhone Storage settings. To see specific offline files, you must manually open the OneDrive app and look for files marked with the 'Make available offline' checkmark.
Does offloading the OneDrive app clear the Documents & Data?
Offloading the app removes the app's core installation files but intentionally preserves 'Documents & Data'. To completely erase the Documents & Data, you must select 'Delete App' instead of 'Offload App'.
