Concatenate Large Number of PDF Files

When working with large collections of PDF files, memory consumption can become a bottleneck during concatenation. Using Aspose.PDF for Python, you can enable disk buffering in the PdfFileEditor class to merge many PDFs efficiently. The concatenate method combines the input files into a single PDF while the disk buffer prevents high memory usage. This approach is ideal for processing bulk documents, automated report generation, or consolidating large PDF archives.

1. Create a PdfFileEditor Object.
2. Merge multiple PDF files.

import aspose.pdf as ap
import aspose.pdf.facades as pdf_facades

import sys
from os import path

sys.path.append(path.join(path.dirname(__file__), ".."))
from config import set_license, initialize_data_dir


def concatenate_large_number_files(files_to_merge, output_file):
    # Create a PdfFileEditor object
    pdf_editor = pdf_facades.PdfFileEditor()
    pdf_editor.use_disk_buffer = True  # Enable disk buffering for large files
    pdf_editor.concatenate(files_to_merge, output_file)
