Monitor Folder Size and Alert When It Exceeds a Certain Limit

In this article, we will explore how to monitor a folder’s size and set an alert when it exceeds a certain limit using Python.

Why Monitor Folder Size?

Monitoring a folder’s size is crucial in various scenarios. For instance, you may need to track the growth of a project’s files or monitor the storage capacity of a server. This can be particularly useful in scenarios where disk space is limited, and it’s essential to prevent the folder from filling up.

How to Monitor Folder Size

To monitor a folder’s size, we can use the `os` module in Python. This module provides a way to interact with the operating system and retrieve information about files and directories. We can use the `os.path.getsize()` function to get the size of a file or directory in bytes.

Python Code Example


import os
import time
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

# Set the path to the folder you want to monitor
folder_path = '/path/to/folder'

# Set the maximum allowed size in bytes
max_size = 100000000  # 100 MB

# Set the email details
email_from = 'your_email@example.com'
email_to = 'recipient_email@example.com'
email_password = 'your_email_password'
email_subject = 'Folder Size Exceeded'

while True:
    # Get the current size of the folder
    folder_size = 0
    for root, dirs, files in os.walk(folder_path):
        for file in files:
            file_path = os.path.join(root, file)
            folder_size += os.path.getsize(file_path)

    # Check if the folder size exceeds the maximum allowed size
    if folder_size > max_size:
        # Send an email alert
        msg = MIMEMultipart()
        msg['From'] = email_from
        msg['To'] = email_to
        msg['Subject'] = email_subject
        body = 'The folder size has exceeded the maximum allowed size.'
        msg.attach(MIMEText(body, 'plain'))
        server = smtplib.SMTP('smtp.gmail.com', 587)
        server.starttls()
        server.login(email_from, email_password)
        server.sendmail(email_from, email_to, msg.as_string())
        server.quit()

    # Wait for 1 hour before checking again
    time.sleep(3600)

Conclusion

In this article, we have explored how to monitor a folder’s size and set an alert when it exceeds a certain limit using Python. By using the `os` module and setting up an email alert system, you can ensure that you receive notifications when the folder size exceeds the maximum allowed size.

This is particularly useful in scenarios where disk space is limited, and it’s essential to prevent the folder from filling up. You can customize the code to suit your specific needs and monitor multiple folders with ease.
