Where Adobe Acrobat Stores Last Session PDF Paths in Windows Registry
Question details
The user needs to find the specific location in the Windows Registry where Adobe Acrobat Pro DC stores the file paths for PDFs that were opened in the current and previous sessions.

- Product
- Adobe Acrobat Pro DC
- Device & OS
- Windows
- Scenario
- Troubleshooting or manually modifying the data used by Acrobat's 'Reopen PDFs from the last session' feature.
- Observed behavior
- Acrobat uses specific registry keys within the SessionManagement folder to store device-independent paths (in hexadecimal) and readable file paths for active PDF sessions.
Before making any modifications in the Windows Registry, always create a registry backup or set a System Restore point, as incorrect changes can negatively impact your system's stability.
Locate Session Data in the Windows Registry Editor
Use the built-in Windows Registry Editor to navigate directly to the Adobe Acrobat SessionManagement keys and identify the stored PDF file paths.
Adobe Acrobat Pro DC records the history of opened PDFs in the current and previous sessions directly within the user's registry hive.
By accessing these keys, you can identify readable file paths, session tabs, and device-independent path values.
Press the Windows Key + R on your keyboard to open the Run dialog. Type 'regedit' into the text box and press Enter.
In the Registry Editor's address bar or via the left sidebar, navigate to the following path: HKCU\Software\Adobe\Adobe Acrobat\DC\SessionManagement\.
Look for the 'cWindowsCurrent' folder to view current-session information, or open the 'cWindowsPrev' folder for the previous session.
Expand Windows-instance folders (such as 'cWin'). Inside, each PDF is represented by a 'cTab' folder and a 'cPathInfo' file. Check the 'tDIText' value to see the readable file path of the PDF document.

Check System Temporary Folders
If you are unable to use the Registry Editor, checking Windows temporary folders may help you locate cached files from your previous PDF sessions.
Easily Access Recent PDFs with WPS Office
Instead of digging into complex Windows Registry keys to track down your previously opened PDFs, use WPS Office. It features an intuitive recent document manager that effortlessly tracks your history across PDFs, Word documents, Excel spreadsheets, and PowerPoint presentations.
- 1. Open WPS Office: Launch the WPS Office application on your Windows computer.
- 2. Access the Recent Tab: On the home screen, click on 'Recent' in the left-hand navigation pane.
- 3. Find Your PDF: Scroll through the chronologically sorted list of your recent files to locate the PDF from your last session.
- 4. Click to Reopen: Click directly on the PDF file name to instantly reopen it right where you left off.

Frequently Asked Questions
How do I stop Acrobat from automatically reopening PDFs from the last session?
You can disable this feature directly within the application. Open Adobe Acrobat, go to Edit > Preferences, select the 'General' category on the left, and uncheck the option labeled 'Open PDFs from last session on Acrobat launch'.
What is the tDIText registry value used for?
In Adobe Acrobat's SessionManagement registry keys, the tDIText value holds the standard, human-readable file path pointing to the exact location of the PDF document on your local drive or network.
Is it safe to delete the SessionManagement registry key to clear history?
While deleting the specific subkeys under SessionManagement usually forces Acrobat to generate fresh ones upon the next launch, manually deleting registry keys carries risks. It is always safer to clear your recent files through the application's interface.
