Question details
The user is unable to open PDF files in Adobe Acrobat Reader because the files display a gray X icon overlay in the corner, and clicking them produces no response.
- Product
- Adobe Acrobat Reader, Cloud Storage (OneDrive)
- Device & OS
- not provided
- Scenario
- Attempting to open a local PDF document that is managed by a cloud synchronization service.
- Observed behavior
- The PDF file fails to launch in the application. It displays an X overlay on its icon, indicating the file is a cloud-only placeholder and has not been downloaded to the local device.
Ensure you have an active internet connection and verify that your cloud storage application (such as Microsoft OneDrive) is running and properly signed in.
Download and Sync Cloud-Only PDF Files
Force the cloud storage application to download the actual PDF file to your local drive so it can be opened by Acrobat Reader.
The gray 'X' icon overlay on your PDF file typically indicates that the document is stored in the cloud (like OneDrive) but has not been synchronized or downloaded to your local computer. Because Adobe Acrobat Reader requires the actual file data to render the document, clicking these placeholder shortcuts will appear to do nothing.
Open File Explorer (Windows) or Finder (Mac) and navigate to the folder where the PDF file with the 'X' icon is stored.
Right-click the PDF file. If you are using OneDrive, select 'Always keep on this device' from the context menu to force the file to download.
Allow the cloud service a few moments to download the file. The 'X' icon should disappear or be replaced by a green checkmark indicating successful synchronization.
Double-click the fully downloaded PDF file. It should now open normally in Adobe Acrobat Reader.

Frequently Asked Questions
What does the X icon on a file or folder mean in Windows?
A gray 'X' icon on a file or folder indicates a synchronization error or that the file is a cloud-only placeholder that hasn't successfully downloaded to your local drive. This is most commonly associated with Microsoft OneDrive or Dropbox sync issues.
Why does Adobe Acrobat Reader do nothing when I try to open these files?
When a file has an 'X' icon, the actual document data is missing from your local storage. Acrobat Reader attempts to open the file path, but because it only finds a cloud shortcut rather than the full PDF data, it fails to launch or display the document.
Can I prevent OneDrive from removing my local PDF files?
Yes. You can disable the 'Files On-Demand' feature in your OneDrive settings, which will force all files to remain downloaded on your local hard drive at all times, preventing the 'X' icon placeholder issue.
How do I clear the X icon if OneDrive is already signed in?
If you are signed in and still see the X icon, right-click the OneDrive cloud icon in your system tray, check for specific sync errors or paused syncing, and click 'Resume syncing'. Alternatively, restarting your computer can refresh the file explorer icons.
