How to Recover a PDF File That Failed to Sync in Adobe Document Cloud
Question details
The user needs to recover a PDF document that became incomplete or decreased in file size due to a synchronization failure with Adobe Document Cloud.

- Product
- Adobe Document Cloud / Acrobat
- Device & OS
- Android
- Scenario
- Uploading changes made to a PDF file to the cloud from an Android device.
- Observed behavior
- The synchronization fails during the upload process, causing the resulting PDF file to appear smaller in file size or have incomplete content.
Immediately stop editing or saving the affected PDF to prevent overwriting the existing data, and ensure your Android device is connected to a stable Wi-Fi network before attempting to re-sync.
Locate Local Backup and Restart Synchronization
Find the temporary or locally saved version of your PDF before attempting to sync to the cloud again.
Open your Android file manager and navigate to your internal storage to look for locally saved versions of the PDF before the sync failed.
Open the Adobe Acrobat app and check the 'Recent' tab for any locally cached versions of your document that might still contain your edits.
Switch to a stable Wi-Fi network, completely close the Acrobat app from your Android multitasking menu, and restart it to re-initiate the sync process securely.

Request Assistance from Adobe Support
If the file is completely missing from local storage, Adobe Support might be able to restore a previous cloud version.

Frequently Asked Questions
Why do PDF files get corrupted or shrink during a cloud sync?
Sync failures often occur due to network interruptions, app crashes, or server timeouts while uploading. This leaves the cloud with an incomplete file package, which appears smaller or corrupted when you try to open it.
Can I recover previous versions of my PDF in Adobe Document Cloud?
Yes, if the file was previously synced successfully, you can log into Adobe Document Cloud via a web browser and check if older versions of the file are available in your version history for download.
Where does Adobe Acrobat for Android store local temporary files?
Local files are typically stored in the app's internal cache or the 'Documents' folder on your Android device. Using a file manager app to search for '.pdf' files modified on the current date can help locate them.
How can I prevent PDF sync failures on my Android device?
Ensure you are on a stable Wi-Fi network before editing large documents, keep the Adobe Acrobat app updated to the latest version, and avoid closing the app forcefully while an upload is in progress.
