You can merge all the PDFs in `D:\pdf` into a single document using PowerShell and the `PdfSharp` .NET library or Python with `PyMuPDF` (`fitz`). Below are two methods:

---

### **Method 1: PowerShell with PdfSharp**
1. Install the `PdfSharp` library if you don???t have it:
   - Download `PdfSharp.dll` from [NuGet](https://www.nuget.org/packages/PdfSharp/)
   - Extract it to `D:\pdf\PdfSharp.dll`

2. Run the following PowerShell script:
   ```powershell
   Add-Type -Path "D:\pdf\PdfSharp.dll"

   $pdfFiles = Get-ChildItem -Path "D:\pdf" -Filter "*.pdf" | Sort-Object Name
   $outputFile = "D:\pdf\Merged.pdf"

   $pdf = New-Object PdfSharp.Pdf.PdfDocument
   foreach ($file in $pdfFiles) {
       $doc = [PdfSharp.Pdf.IO.PdfReader]::Open($file.FullName, [PdfSharp.Pdf.IO.PdfDocumentOpenMode]::Import)
       foreach ($page in $doc.Pages) {
           $pdf.AddPage($page)
       }
   }
   $pdf.Save($outputFile)
   Write-Host "Merged file saved to $outputFile"
   ```

---

### **Method 2: Python with PyMuPDF (`fitz`)**
If you have Python installed, install `PyMuPDF`:
```sh
pip install pymupdf
```
Then, use this script to merge the PDFs:
```python
import fitz
import os

pdf_folder = r"D:\pdf"
output_pdf = r"D:\pdf\Merged.pdf"

pdf_files = sorted([f for f in os.listdir(pdf_folder) if f.endswith(".pdf")])

merged_doc = fitz.open()
for pdf in pdf_files:
    with fitz.open(os.path.join(pdf_folder, pdf)) as doc:
        merged_doc.insert_pdf(doc)

merged_doc.save(output_pdf)
print(f"Merged PDF saved to {output_pdf}")
```
