Python File Sorting Script

A Python script that scans files in a directory and sorts them into subject-specific folders based on keyword matching.

How It Works

The script reads filenames and checks for subject keywords (Biology, Chemistry, Physics, Maths, etc.). It then moves each file into the corresponding folder.

Script

python
import os
import shutil

# Define subject folders and their keywords
subject_map = {
    "Biology": ["bio", "biology"],
    "Catechism": ["catechism", "cate"],
    "Chemistry": ["chem", "chemistry"],
    "Computer Science": ["computer", "cs", "comp"],
    "English": ["english", "eng"],
    "General": ["general"],
    "Maths": ["maths", "math", "mathematics"],
    "Physics": ["physics", "phy"],
}

source_dir = "."  # change to your target folder

for filename in os.listdir(source_dir):
    if os.path.isfile(os.path.join(source_dir, filename)):
        name_lower = filename.lower()
        for subject, keywords in subject_map.items():
            if any(kw in name_lower for kw in keywords):
                dest_dir = os.path.join(source_dir, subject)
                os.makedirs(dest_dir, exist_ok=True)
                shutil.move(
                    os.path.join(source_dir, filename),
                    os.path.join(dest_dir, filename)
                )
                print(f"Moved {filename} -> {subject}/")
                break

Usage

1. Save the script as sort_files.py in the folder containing your unsorted files
2. Update the subject_map with your own subjects and keywords
3. Run python sort_files.py
