How to Process Only PDF Files in Acrobat Pro DC Action Wizard
Question details
The user wants to run a batch process exclusively on PDF files using Acrobat Pro DC Action Wizard, preventing it from incorrectly modifying non-PDF files located in the same folder hierarchy.

- Product
- Adobe Acrobat Pro DC
- Device & OS
- Windows
- Scenario
- Scanning a folder hierarchy containing mixed file types to batch-process only the PDF documents.
- Observed behavior
- Action Wizard fails to filter by file type reliably, processing and potentially modifying non-PDF files instead of ignoring them.
Verify you have sufficient disk space on your drive to create a complete temporary copy of your PDF files and their folder hierarchy before running the batch action.
Isolate PDF Files Using a Temporary Directory via Command Line
Since Action Wizard's native filtering can be unreliable for nested folders, the safest method is to copy only your PDF files into a separate folder, process them, and then transfer the results back.
This workaround relies on the Windows XCOPY command to safely duplicate only the target .pdf files while perfectly maintaining your original folder hierarchy.
By pointing Acrobat's Action Wizard to this isolated temporary directory, you guarantee that no other file types will be mistakenly processed or corrupted during the batch operation.
Press the Windows key, type 'cmd' into the search bar, and hit Enter to launch the Command Prompt.
Execute a command to copy only PDFs to a new folder. For example, type: XCOPY "C:\utils\*.pdf" "D:\Backup\utilspdfs" /s /i and press Enter.
Open Acrobat Pro DC, launch the Action Wizard, and select the newly created temporary directory (e.g., D:\Backup\utilspdfs) as your target folder for the batch process.
Once the Action Wizard completes the batch process, copy the newly updated PDF files from the temporary folder back into your original source directory, replacing the old versions.

Frequently Asked Questions
Why does Acrobat Action Wizard process non-PDF files?
In certain versions of Acrobat Pro DC, the built-in file filtering functionality may not reliably exclude non-PDF formats when scanning deeply nested folder hierarchies, leading to unintended file modifications.
Is there a way to filter files directly within Action Wizard without using Command Prompt?
While Action Wizard provides options to specify file extensions within its settings, users frequently report this failing on folders containing mixed file types. The command-line isolation method remains the most foolproof workaround.
Can I perform this PDF isolation trick on a Mac?
Yes. On macOS, you can use the Terminal and combine the 'find' and 'cp' commands (e.g., find . -name '*.pdf' -exec cp --parents {} /target/dir \;) to mirror the folder structure and isolate PDF files before running the batch action.
Will copying the files back overwrite my original PDFs?
Yes, if you copy the processed files back to the exact same source directory with the same filenames, it will overwrite the original, unprocessed PDFs. Always ensure you have a backup if you need to retain the original files.
