Folder Synchronization Program

A program that maintains a replica of a source folder, performing periodic one-way synchronization.

Description

This tool synchronizes two folders by maintaining an exact copy of a source folder in a replica folder. All file operations (creation, copying, removal) are logged both to a file and console output.

Features

• One-way folder synchronization
• Periodic updates at specified intervals
• Operation logging to file and console
• Support for nested folders
• File comparison using MD5 hashing

Requirements

• Python 3.10+
• Standard library only

Usage

python main.py source_folder replica_folder log_folder interval

Where:

• source_folder: Path to source directory
• replica_folder: Path to replica directory
• log_folder: Path to store log files
• interval: Time between syncs in seconds

Example:

python main.py ./Source_Folder ./Replica_Folder ./Log_File_Folder 60

Implementation Details

The program consists of two main components:

• main.py: Handles command-line arguments and program initialization
• folders_sync.py: Contains the core synchronization logic

The synchronization process:

1. Scans source and replica folders
2. Identifies files to create, update, or remove
3. Performs necessary operations
4. Logs all actions
5. Waits for specified interval before next sync

Notes

• Log folder must be separate from source and replica folders
• Sync interval must be greater than 0
• Source and replica folders must exist and be different
• Program can be stopped with Ctrl+C
