How to OCR PDF Files in Network Folders Using Adobe Acrobat
Question details
The user needs to make hundreds of PDF files searchable using OCR, but the files are stored across multiple subfolders on a network drive.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Batch processing multiple PDF files located on a network drive to apply Optical Character Recognition (OCR) and make them fully searchable.
- Observed behavior
- Acrobat fails to display network folders in the OCR selection dialog or cannot process the files due to mapped-drive limitations, permissions, or security restrictions.
Ensure you have full read and write permissions for the network directory and verify that your network connection is stable before initiating batch OCR processes.
Copy Network PDFs to a Local Drive for Processing
Moving files to a local directory temporarily bypasses network permissions and mapped-drive restrictions in Acrobat.
Adobe Acrobat often restricts automated processes on network drives due to strict sandbox security and user permission conflicts. Processing files locally ensures maximum stability and speed during large batch OCR tasks.
Open your computer's File Explorer, navigate to the network drive containing your PDFs, right-click the parent folder containing the subfolders, and select Copy.
Navigate to a local drive folder such as your Desktop or Documents, right-click, and select Paste to transfer all the files locally.
Open Adobe Acrobat, go to Tools > Action Wizard, and select Make Searchable (OCR). Add your local folder to the file list and execute the batch process.
Once the OCR process finishes successfully, copy the updated, searchable PDF files back to their original location on the network drive to replace the unsearchable ones.
Add Network Location to Acrobat Trusted Paths
Configure Acrobat's security preferences to trust your network drive, allowing direct OCR processing without moving files.
OCR PDFs Effortlessly with WPS Office
If Adobe Acrobat struggles with network drives or complex security policies, you can bypass these issues and make your PDFs searchable directly using the advanced OCR feature in WPS Office.
- 1. Open WPS Office: Launch WPS Office on your computer and open the PDF tab.
- 2. Select the OCR tool: Navigate to the Tools tab on the top ribbon and click on the OCR button to launch the recognition utility.
- 3. Configure OCR settings: Add your files, including those from network drives, and choose to save the output as a searchable PDF document.
- 4. Run and save: Click confirm to start the OCR process. WPS Office will process the files and save the searchable PDFs directly to your desired location.
Frequently Asked Questions
Why does Adobe Acrobat hide my network folders during the OCR selection?
Acrobat's Enhanced Security mode often blocks untrusted network paths by default to prevent malicious scripts from executing. Additionally, if Acrobat is running with elevated administrator privileges, it may not see network drives mapped under your standard user profile.
Can I batch process multiple subfolders for OCR in Acrobat?
Yes, you can use the Action Wizard tool in Adobe Acrobat to batch process a parent folder and all its subfolders. However, when doing this on a network drive, ensure the drive is properly mapped and added to Acrobat's Privileged Locations.
Does WPS Office support making PDFs searchable?
Yes, WPS Office includes a powerful built-in OCR feature that can quickly convert scanned PDFs and images into fully searchable PDF files or editable Word documents.
