How to Solve Issues with -detach-embedded-files in VeryPDF PDF Extract Tool When File Names Contain Spaces

Extracting embedded files from PDFs is an essential task for many business users dealing with electronic invoices, XRechnung, Factur-X, or similar standards. VeryPDF PDF Extract Tool Command Line provides a powerful and flexible way to extract various elements from PDF files—including attachments—using simple command-line parameters.

One of the popular features is the -detach-embedded-files parameter, which allows users to automatically extract files embedded within a PDF document. However, some users have reported strange behavior when using this feature under specific conditions. This article addresses one such scenario and provides a clear explanation and solution.

How to Solve Issues with -detach-embedded-files in VeryPDF PDF Extract Tool

The Problem: -detach-embedded-files Seems to Work Only on Second Attempt

One of our users, Thomas, recently encountered a confusing issue:

“When I call pdfextract with the parameter -detach-embedded-files, I receive exit code 0 with both PDF files, but no files are extracted on the first attempt. If I run the same command a second time, it works fine. When I remove the -detach-embedded-files parameter, all files are extracted correctly.”

Here are the examples Thomas provided:

First Run:

pdfextract.exe -detach-embedded-files -outfolder D:\Downloads\1 D:\Downloads\Aufinger-Rechnung-Mail_225047.pdf
[Message] Register "VeryPDF PDF Extract Tool Command Line" successful.
[Extract Embedded File] #1 Save to "D:\Downloads\1/factur-x.xml" file.

pdfextract.exe -detach-embedded-files -outfolder D:\Downloads\1 D:\Downloads\Rechnung-2500714-eRechnung-PDF.pdf
[Message] Register "VeryPDF PDF Extract Tool Command Line" successful.
[Extract Embedded File] #1 Save to "D:\Downloads\1/xrechnung.xml" file.

The output seems successful, but Thomas found that the files only truly extracted on a second run—or with different parameters.

The Root Cause: Spaces in File Paths or File Names

This unusual behavior is caused by spaces in the file path or file name. In Tobias's case, both input PDF files had spaces in their names, such as:

  • Aufinger Rechnung Mail_225047.pdf
  • Rechnung 2500714 eRechnung PDF.pdf

While these names may appear fine on the surface, when used in a command-line context without proper quotation marks, spaces can cause the command-line parser to misinterpret arguments. This issue doesn't always manifest in normal operations but becomes problematic when using certain flags—like -detach-embedded-files.

The Solution: Remove Spaces or Use Quotation Marks

There are two effective ways to solve this problem:

✅ Option 1: Enclose Paths in Double Quotes

When calling the tool, wrap all file paths and output folder parameters in double quotes:

pdfextract.exe -detach-embedded-files -outfolder "D:\Downloads\1" "D:\Downloads\Aufinger Rechnung Mail_225047.pdf"

This prevents the command-line interpreter from breaking the file path into invalid parts due to spaces.

✅ Option 2: Rename Files to Remove Spaces

Rename the file to avoid using spaces in the file name:

  • ❌ Rechnung 2500714 eRechnung PDF.pdf
  • ✅ Rechnung-2500714-eRechnung-PDF.pdf

Then your command becomes simpler and less error-prone:

pdfextract.exe -detach-embedded-files -outfolder D:\Downloads\1 D:\Downloads\Rechnung-2500714-eRechnung-PDF.pdf

Both of these methods will ensure -detach-embedded-files works reliably on the first attempt.
