Bulk File Downloader

This script allows you to download multiple files from URLs listed in a .txt file. It utilizes multithreading to perform downloads concurrently, enhancing performance. The script also includes functionality for retrying failed downloads and logging errors.

Features

  • Multithreaded Downloads: Accelerates the download process by downloading multiple files simultaneously.
  • Randomized User-Agent Headers: Helps avoid being blocked by websites by using a variety of user-agent headers.
  • Retry Mechanism: Automatically retries failed downloads up to 3 times.
  • Progress Bar: Displays download progress using tqdm.
  • Error Logging: Logs failed download attempts and errors to separate files.

Prerequisites

Ensure you have the following Python packages installed:

  • requests for handling HTTP requests.
  • tqdm for displaying a progress bar.

You can install these packages using pip:

pip install requests tqdm

Usage

Prepare the URL List: Create a .txt file (e.g., 1.txt) containing the URLs of the files you want to download. Each URL should be on a new line.

Run the Script: Run the script using Python:

python download.py

The script will read the URLs from the .txt file, download the files, and save them to the specified output directory.

Example

Create a file named 1.txt with the following content:

https://example.com/file1.zip
https://example.com/file2.zip

Run the script:

python bulk_file_downloader.py

The downloaded files will be saved to the downloads folder.

Parameters

  • txt_file: The name of the .txt file containing the list of URLs.
  • output_dir: The directory where the downloaded files will be saved.

Log Files

  • failed.txt: Contains URLs that failed to download after all retry attempts.
  • errors.txt: Contains errors that occurred during the download process, including the corresponding URLs.

Customization

  • Retries: You can adjust the number of retry attempts for failed downloads by modifying the retries argument in the download_file function.
  • **Headers: The headers_list can be customized to add or remove user-agent headers.

Notes

Ensure that the URLs in the .txt file are valid and accessible. The script automatically creates the output directory if it doesn't exist.
