How to Fix Acrobat DC Opening Only One PDF at a Time
Question details
The user wants to configure Acrobat DC to open multiple PDFs in new tabs simultaneously rather than being restricted to viewing a single document at a time.

- Product
- Adobe Acrobat DC
- Device & OS
- not provided
- Scenario
- Opening new PDF files or email attachments when another document is already open in the application.
- Observed behavior
- New PDFs do not open automatically. The user is forced to close the existing document first or open the new file manually from within the software.
Ensure you have saved any unsaved changes in your currently open PDF documents, as adjusting these preferences will require you to restart the application.
Enable Tabbed Viewing in Acrobat Preferences
Adjusting the document preferences is the most direct way to ensure multiple PDFs open in separate tabs within the same window.
When upgrading from older versions like Acrobat Reader, specific viewing preferences might be reset or changed. Enabling the tabbed interface allows for a smoother workflow when handling multiple documents.
Launch Adobe Acrobat DC. Click on 'Edit' in the top menu bar, and select 'Preferences' from the dropdown list.
In the left-hand sidebar of the Preferences dialog box, locate and click on the 'Documents' category.
Look under the 'Open Settings' section and check the box next to 'Open documents as new tabs in the same window (requires restart)'.
Click 'OK' at the bottom of the window to save your changes, then completely close and reopen Acrobat DC for the setting to take effect.

Verify Default App Status and Update Acrobat
Ensure Acrobat is fully recognized by your operating system and email client as the default handler for PDF attachments.
Open Multiple PDFs Seamlessly with WPS Office
If you are tired of applications struggling to manage multiple files, WPS Office offers a powerful built-in PDF reader that natively organizes multiple documents in a clean, tabbed interface within a single lightweight window.
- 1. Download and Install WPS Office: Visit the official WPS Office website to download the free suite and follow the installation instructions.
- 2. Set as Default PDF Reader: Right-click any PDF file on your computer, choose 'Open with', select WPS Office, and check 'Always use this app to open .pdf files'.
- 3. Enjoy Tabbed Viewing: Double-click multiple PDFs or email attachments; they will seamlessly open as separate tabs within the same WPS Office window.

Frequently Asked Questions
Why did my PDFs stop opening in tabs after an update?
Major software updates or upgrading from Adobe Reader to Acrobat DC can sometimes reset custom preferences to their default settings. You will need to manually re-enable the tabbed document setting in the Preferences menu.
Can I view two tabs side by side in the same window?
Yes. If tabbed viewing is enabled, you can click and drag a tab out to create a new window, or use the 'Window' > 'Tile' options in Acrobat to view multiple open tabs side by side.
Why won't my email attachments open automatically even with tabs enabled?
This usually indicates a communication error between your email client and the PDF software. Setting your PDF reader as the absolute default app in your system settings usually resolves this issue.
