How to Delete Unknown ZIP Files in Acrobat on iPhone
Product
Adobe Acrobat, Dropbox
Device & OS
iPhone (iOS)
Scenario
Attempting to remove unwanted synced cloud files from the Acrobat app interface.
Observed behavior
An unexpected ZIP file appears and updates automatically within Acrobat, and it cannot be deleted directly from the app's local interface.
Before you start

Before deleting the ZIP file from its source location, ensure that you have backed up any important writing documents it may contain, as deleting it from the cloud will remove it permanently across all connected devices.

Solution 1Recommended

Delete the File from the Connected Cloud Storage Source

Since Acrobat syncs files from external cloud services, deleting the file directly from the source (such as Dropbox) is the most effective way to remove it from the app.

Adobe Acrobat on iOS often links to external cloud drives. When a file is synced rather than stored locally, Acrobat restricts direct deletion to prevent accidental data loss across platforms.

1
Open your cloud storage app

Launch the Dropbox app on your iPhone, or log in via a web browser using the account connected to your Acrobat app.

2
Locate the ZIP file

Use the search bar or browse your recent files to find the unknown ZIP file containing the writing documents.

3
Delete the file permanently

Tap the options menu (usually represented by three dots) next to the ZIP file and select 'Delete' to remove it from the cloud server.

Frequently Asked Questions

Why can't I delete files directly from the Acrobat iOS app?

If a file is synced from a third-party cloud service like Dropbox or Google Drive, Acrobat only displays a mirrored version of it. To permanently delete the file, you must remove it from the original cloud storage provider.

How do I stop Acrobat from automatically syncing files?

You can stop automatic synchronization by disconnecting external cloud storage accounts. Go to the 'Files' tab, tap on 'Locations', and sign out of or remove the connected services.

Can an unknown ZIP file contain a virus on my iPhone?

While iOS is highly secure and sandboxes applications, it is best practice not to extract or interact with unknown ZIP files. Deleting the file directly from the source cloud storage ensures your environment remains clean.

Why does the deleted file keep reappearing in Acrobat?

This usually happens due to a synchronization delay or if the file was only deleted locally but remained on the cloud server. Ensure you delete the file via the cloud provider's official app or website, then refresh Acrobat.
