TwinTrim

TwinTrim is a powerful and efficient tool designed to find and manage duplicate files across directories. It provides a streamlined way to scan files, identify duplicates based on their content, and remove them automatically or with user guidance, helping you save storage space and keep your file system organized.

Table of Contents

Features

  • Duplicate Detection: Scans directories to detect duplicate files based on file content rather than just filenames.
  • Automatic or Manual Removal: Choose to handle duplicates automatically using the --all flag or manually select which files to delete.
  • Customizable Filters: Set filters for minimum and maximum file sizes, file types, and specific filenames to exclude from the scan.
  • Multi-Threaded Processing: Utilizes multi-threading to quickly scan and process large numbers of files concurrently.
  • Deadlock Prevention: Implements locks to prevent deadlocks during multi-threaded operations, ensuring smooth and safe execution.
  • User-Friendly Interface: Offers clear prompts and feedback via the command line, making the process straightforward and interactive.

How It Works

Core Components

  1. File Metadata Management:

    • Uses AllFileMetadata and FileMetadata classes to manage file information, such as modification time and file paths.
    • Maintains metadata in two dictionaries (store and normalStore) for handling different levels of duplicate management.

  2. File Hashing:

    • Generates a unique hash for each file using MD5 to identify duplicates by content.

  3. File Filtering:

    • The FileFilter class provides functionality to filter files based on size, type, and exclusions.

  4. Duplicate Handling:

    • Duplicate files are identified by comparing their hashes.
    • Based on file modification time, the latest file is retained, and older duplicates are removed.

  5. Deadlock Prevention:

    • Uses locks within multi-threaded processes to ensure that resources are accessed safely, preventing deadlocks that could otherwise halt execution.

Key Functions

  • add_or_update_file: Adds new files to the metadata store or updates existing entries if a duplicate is detected.
  • add_or_update_normal_file: Similar to add_or_update_file but manages duplicates in a separate store.
  • handleAllFlag: Handles duplicate removal automatically without user intervention.
  • find_duplicates: Finds duplicate files in the specified directory and prepares them for user review or automatic handling.

Usage

Command Line Interface

Run the script using the following command:

python -m twinTrim.main <directory> [OPTIONS]

Options

  • --all: Automatically delete duplicates without asking for confirmation.
  • --min-size: Specify the minimum file size to include in the scan (e.g., 10kb).
  • --max-size: Specify the maximum file size to include in the scan (e.g., 1gb).
  • --file-type: Specify the file type to include (e.g., .txt, .jpg).
  • --exclude: Exclude specific files by name.
  • --label-color: Set the font color of the output label of the progress bar.
  • --bar-color: Set the color of the progress bar.

Examples

  1. Automatic Duplicate Removal:

    python -m twinTrim.main /path/to/directory --all

  2. Manual Review and Removal:

    python -m twinTrim.main /path/to/directory

  3. Filtered Scan by File Size and Type:

    python -m twinTrim.main /path/to/directory --min-size "50kb" --max-size "500mb" --file-type "txt"

Dependencies

  • Python 3.6+
  • click for command-line interaction
  • tqdm for progress bars
  • concurrent.futures for multi-threaded processing
