- Product

- Device & OS
- not provided
- Scenario
- Opening a new PDF document

Ensure you have saved any unsaved changes in your currently open PDFs before modifying Acrobat's startup preferences, as you will need to restart the application.
Disable Restore Last Session Preferences in Acrobat
Turn off the settings that prompt Acrobat to remember and reopen documents from your previous session.
Adobe Acrobat includes a feature designed to pick up where you left off by restoring your previous session. Disabling this feature ensures that only the specific PDF file you click on will open.
Launch Adobe Acrobat and navigate to 'Edit' in the top menu bar, then select 'Preferences'. On macOS, click 'Acrobat' in the top left and select 'Preferences'.
In the Preferences window, select 'General' from the Categories menu on the left pane.
Locate the option labeled 'Open documents as new tabs in the same window' or 'Restore last session settings when quitting' (the exact wording varies by Acrobat version) and uncheck the box.
Click 'OK' at the bottom to save your changes. Close all currently open PDF tabs completely, then exit and restart Acrobat to ensure the setting takes effect.

Frequently Asked Questions
Why does Acrobat keep opening old files even after I closed them?
This usually happens because Acrobat is configured to restore your previous session upon startup. If the application was forced to close or if the setting is enabled, it attempts to reopen the tabs that were active right before it was last terminated.
Can I force Acrobat to open multiple PDFs in separate windows instead of tabs?
Yes. Navigate to Edit > Preferences > General, and uncheck 'Open documents as new tabs in the same window'. This forces each newly opened PDF to launch in its own separate window.
How do I clear the recent files list in Acrobat to prevent them from showing up?
You can clear your recent files by opening Acrobat, navigating to the 'Home' or 'Recent' view, selecting the files you want to remove, and choosing 'Remove from Recent' from the right-click context menu.
