How to Fix Adobe Acrobat Opening the Previous PDF Instead of the Selected File
Question details
The user needs to resolve a glitch where Adobe Acrobat loads the previously opened document instead of the newly selected PDF.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Opening a new PDF file from local storage while Acrobat is either closed or already running in the background.
- Observed behavior
- A few seconds after double-clicking the selected PDF, the application unexpectedly switches to or displays the last viewed document instead of the new one.
Make sure you save any unsaved work in your currently open PDFs and fully close Adobe Acrobat via your system's Task Manager or Activity Monitor before attempting these fixes.
Clear Acrobat Preferences and Update the Software
Resetting Adobe Acrobat preferences and installing the latest patches can resolve deep-rooted caching glitches that cause the wrong file to load.
Acrobat stores temporary session data to load files faster. When this preference cache becomes corrupted, the application might mistakenly restore an old session instead of rendering the newly requested file.
Ensure Adobe Acrobat is completely closed. On Windows, use Task Manager (Ctrl + Shift + Esc) to end any background processes named 'Acrobat.exe'.
On Windows, press Win + R, type '%APPDATA%\Adobe\Acrobat', and hit Enter. On Mac, navigate to Library/Preferences in your user folder.
Find the folder named after your Acrobat version (e.g., 'DC' or '2020') and rename it to 'DC_old'. This forces Acrobat to generate fresh, error-free preference files on the next launch.
Open Adobe Acrobat, navigate to 'Help' > 'Check for Updates' in the top menu, and install any available patches. Restart your computer and test opening a new PDF.

Verify File Associations and Default App Settings
Re-establishing the default PDF handler ensures that the operating system correctly passes the new file parameters to the application.
Isolate the Issue by Testing Different Files
Determine whether the document itself is corrupted or triggering a script that redirects the view.

Frequently Asked Questions
Why does my PDF reader keep reopening the last viewed document?
This is typically caused by a corrupted application preference cache or a glitch in the software's session management, which mistakenly restores the previous working state instead of rendering the new file requested by the operating system.
Will reinstalling the application fix the incorrect file opening issue?
Yes, a clean reinstallation can resolve deep-rooted registry and caching issues. Be sure to completely delete your AppData preferences folder after uninstalling to ensure all corrupted temporary files are removed.
Is there a setting to stop the app from remembering my last opened files?
In most PDF readers, including Acrobat, you can navigate to Edit > Preferences > Documents. Under 'Open Settings', you can adjust or uncheck options related to restoring last view settings when reopening documents.
How can I provide helpful details to support teams for this glitch?
Use a screen recording application to capture the moment you open the intended file and the subsequent switch to the older file. Provide this video along with your operating system version and the exact version number of your PDF software.
