File Explorer PDF Preview Is Showing “Index Of” Instead of Preview
Update Adobe Acrobat
Install the latest updates for Adobe Acrobat, and check if this quick workaround solves the problem for you. Launch Adobe Acrobat, click on the Help menu, and select Check for updates. Hit the Download button to install the available updates. Restart the program and check if you can preview PDF files.
Check the Filename
Check if the file path or filename contains the number sign (#). Sometimes, the Microsoft PDF Previewer might simply ignore the path that comes after the number sign.
To make things worse, if the number sign is the first character of a filename, the PDF Previewer may display the thư mục index, instead of previewing the file.
The quickest solution to solve the problem is to remove the number sign from the filename. However, that may not always be possible. If you don’t have permission to edit the filename, contact your IT admin for further help.
Enable a Different PDF Previewer
Enable a different PDF previewer and check if this solution solves the problem.
Open the Registry Editor Navigate to HKEY_CLASSES_ROOT.pdfShellEx8895b1c6-b41f-4c1c-a562-0d564250836fDefault Locate the 3A84F9C2-6164-485C-A7D9-4B27F8AC009E key which is the Microsoft PDF Previewer
Change it to a different preview handler
To check what preview handlers are available on your machine, go to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPreviewHandlers. Simply copy the value of your preferred preview handler and use it to tweak your Registry settings as shown above.
For example, if you’re using the Foxit PDF Preview Handler, you can use this key: 1B96FAD8-1C10-416E-8027-6EFF94045F6F. If you’re using Adobe Reader, the key to use is this: DC6EFB56-9CFA-464D-8880-44885D7DC193.
Conclusion
If your computer can’t preview PDF files, showing an index file directory instead, make sure to update Adobe Acrobat. Then, check if the filename contains the number sign and remove it. If the issue persists, tweak your Registry settings and enable a different PDF previewer.
Which of these solutions solved the problem for you? Let us know in the comments below.

Unable to preview PDF files in Windows 10 Explorer or MS Outlook with Power PDF 3.0
This can happen if the necessary registry keys were not generated when Power PDF was installed. Sometimes Windows Security prevents our software from modifying the registry during the installation. The resolution is to manually create the necessary registry keys.
Attached is a .reg file that creates the necessary registry keys for v3.0. Please note that this file contains the path to the installation thư mục for Power PDF in two places and it may need to be modified to match the path the client site. Specifically, the newest installation of Power PDF 30 puts two spaces between "Power PDF" and "30". Be sure the path matches the system on which you are using this file.
The file has a .txt the end so it can be edited and emailed - remove this extension and click on the .reg file to merge it into the registry of the workstation. Once the registry file is loaded, open taskmanager and restart Windows Explorer. The previews should be working now.

In your Windows computer, File Explorer may not display PDF thumbnails, and instead, show only the default icon assigned for PDF files. This might happen even if you have the option Always show icons, never thumbnails unchecked in the View tab of the Folder Options dialog.
::BEFORE:: — No thumbnail and preview for PDF files
Also, in Microsoft Outlook you’ll see the error when viewing emails that contain PDF file attachments:
The file cannot be previewed because there is no previewer installed for itThis article tells you how to enable PDF thumbnails as well as the PDF preview capability (for the Preview pane) in File Explorer and Microsoft Outlook. The first method (PowerToys) works whether or not you’re using a third-party PDF viewer (e.g., Adobe PDF Reader or Foxit Reader).

[Fix] PDF Thumbnail and Preview Not Showing in Explorer
Preliminary step – Enable thumbnails and preview handlers in Explorer
Open Folder Options Enable “Show preview handlers in preview pane” Uncheck “Always show icons, never thumbnails”
Click OK and close Folder Options.
If thumbnail and preview functionality is still missing for PDF file types, proceed to the next step.
Using Microsoft PowerToys
Microsoft PowerToys is a set of utilities for power users to tune and streamline their Windows 10 experience for greater productivity. PowerToys requires Windows 11 or Windows 10 v1903 (18362) or newer to work.
You can use Microsoft PowerToys to enable PDF thumbnails and preview generation (for the preview pane) even if you don’t have a proprietary PDF viewer software installed. There is no 32-bit version of Microsoft PowerToys; only the 64-bit version has been released.
PowerToys includes a PDF thumbnail generator as well as the preview handler module (DLL). Thus, it works even if you’re using the Windows default PDF viewer (Microsoft Edge browser) for opening PDF files.
To enable thumbnail generation and preview capabilities for PDF files:
Download Microsoft PowerToys via the Microsoft Store. Launch Microsoft PowerToys as administrator (Run as administrator) In PowerToys Settings, select “File Explorer add-ons” in the left pane.
Turn on the “Enable PDF (.pdf) preview” setting.
Turn on the “Enable PDF (.pdf) thumbnails” setting.
Close or minimize Microsoft PowerToys.
Note: PowerToys need not be running in the background in order for the PDF preview and thumbnail feature to work. You can exit PowerToys if you want.
Here you go! The thumbnails and preview pane capability for PDF files are now restored.
::AFTER:: — Thumbnail and preview generation enabled for PDF files
2022 update: Microsoft PowerToys also has the capability to enable thumbnails for .gcode, .md, and .svg file types. It can also enable preview pane functionality for .gcode, and .svg file types.

There is an additional step needed to enable the PowerToys preview handler in Outlook.
Open an admin Command Prompt window and run this command:
reg add "HKLMSOFTWAREMicrosoftWindowsCurrentVersionPreviewHandlers" /v "07665729-6243-4746-95b7-79579308d1b2" /d "Pdf Preview Handler" /t REG_SZ Outlook 32-bit Registry Fix (for Microsoft PowerToys users)Microsoft PowerToys is a 64-bit program. So, its PDF preview handler above won’t be listed in the Outlook 32-bit Trust Center settings as the WOW6432Node registration would be missing by default and also causes the following error in Microsoft Outlook 32-bit:
This file cannot be previewed because there is no previewer installed for it.To make the PowerToys’s PDF preview handler work in Outlook 32-bit, you need to apply the following registry fix. Once done, it gets listed in the Trust Center settings and you should be able to preview PDF attachments in your email.

Using Adobe Acrobat Reader
Adobe Acrobat Reader includes the thumbnail extractor as well as a preview handler shell extension which generates PDF thumbnails as well as file preview in the Preview pane in File Explorer. PDF thumbnails can be enabled or disabled via Adobe Reader’s Preferences dialog.
Enable or Disable PDF “Thumbnails” in File Explorer via Adobe PreferencesOpen Adobe Reader, click Edit, Preferences. Under “General”, enable the option Enable PDF thumbnail previews in Windows Explorer.
Note: If you’ve chosen to disable PDF thumbnails, existing PDF files may still show thumbnail preview from the cache. The thumbnail cache needs to cleared using Disk Cleanup.
PDF Thumbnails and Previews after installing Adobe Reader DC. When you install (or reinstall) Adobe Acrobat Reader DC, the thumbnail extractor, as well as the Preview handler, are registered automatically.
To disable PDF file preview in the File Explorer preview pane, use these steps:
Launch Regedit.exe and navigate to the following branch: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPreviewHandlers From the File menu, choose Export… and backup the branch to a REG file. Right-click the GUID for Adobe PDF Preview Handler which is usually DC6EFB56-9CFA-464D-8880-44885D7DC193 and choose Delete. Click Yes when asked for confirmation. Exit the Registry Editor. Log off and login back for the change to take effect.To enable PDF Preview handler, add the value DC6EFB56-9CFA-464D-8880-44885D7DC193 back or merge the REG file you backed up in Step 4 above.
Automate Using REG Files
To automate enabling or disabling PDF previews as well as PDF thumbnails in File Explorer, you can use these .REG files. Download pdf-thumb-preview.zip, unzip, and extract the files to desktop. Run the appropriate REG file to enable or disable PDF thumbnails, enable or disable PDF preview in File Explorer Preview pane.
As an alternative to manual registry editing, you can use the Preview Handler Association Editor to enable or disable preview for certain file types.
Using Foxit Reader
If you’re using Foxit PDF Reader, re-run the Foxit installer, choose Custom setup and then and enable “Shell extensions” during setup.
Enabling “Shell Extensions” ensures that the Foxit preview/thumbnail extractor module (DLLs) are installed.

The official documentation tells you how to register the Foxit thumbnail handler shell extension FoxitThumnailsHndlr.dll or FoxitThumbnailHndlr_x64.dll (which Foxit setup does it automatically, anyway). Please note that you’ll always need to use the administrator Command Prompt to register DLL files.

C:Program Files (x86)MicrosoftEdgeApplicationnn.n.nnnn.nnPdfPreviewPdfPreviewHandler.dllMicrosoft Edge (Chromium) reinstall/update process should set the above PDF preview handler as the default. If not, you can set it manually by running the following command from an admin Command Prompt window:
reg add HKCR.pdfshellex8895b1c6-b41f-4c1c-a562-0d564250836f /ve /d "3A84F9C2-6164-485C-A7D9-4B27F8AC009E" /fHere you go! The PDF preview generated by Microsoft Edge’s preview handler.
Note: Microsoft Edge PDF previewer has a crazy bug where it throws the “File not found” error if the file or thư mục name contains the # symbol. Microsoft Edge’s current version is 101.0.1210.32 as of this post, and the issue is still unresolved. This problem is covered in the article PDF Preview Shows Directory Index or ERR_FILE_NOT_FOUND
The above module (PdfPreviewHandler.dll) provides PDF preview functionality in File Explorer. However, it doesn’t include a thumbnail generation feature. As a workaround, you can borrow Adobe Acrobat DC’s thumbnail handler (if it’s installed) even though you set Edge as the default viewer. To do so, tải về and run the following registry fix:
