Introduction
In today’s world, data management has become a crucial aspect of businesses. Transfer of data from one system to another is an essential part of data management. FTP (File Transfer Protocol) servers are widely used for the transfer of large amounts of data. In Python, we can use the ftplib module to access and manipulate files on FTP servers. In this article, we will discuss how to retrieve the modify time of files from FTP using Python with the help of the ftplib module.
Importing the ftplib module
Before we dive into the process of retrieving file modification times from an FTP server, we need to import the ftplib module into our Python environment. The ftplib module comes pre-installed with the standard Python distribution, so you don’t need to install it separately.
Connecting to the FTP server
The first step in retrieving a file’s modification time from an FTP server is to connect to the server. We need to establish a connection to the server before we can start accessing its contents. We create an object of the FTP class and use the connect() method to establish a connection to the server. We pass the server address and port number as arguments to the connect() method.
Logging in to the FTP server
Once we have established a connection to the FTP server, we need to log in to the server using our credentials. We use the login() method to log in to the server. We pass our username and password as arguments to the login() method. If the login is successful, the server returns a message indicating the successful login.
Retrieving the list of files on the FTP server
After logging in to the FTP server, we can retrieve the list of files and directories present on the server. We use the nlst() method of the FTP class to retrieve the list of files on the server. The nlst() method returns a list of filenames present on the server.
Filtering the files based on modification time
Once we have retrieved the list of files on the FTP server, we can filter the files based on their modification times. We use the dir() method of the FTP class to retrieve the details of a specific file on the server. The dir() method returns a string containing the details of the file. We can extract the modification time of the file from this string and compare it with the desired time range.
Retrieving the modify time of a file from FTP server
We can retrieve the modify time of a file from an FTP server using the MDTM command provided by the FTP protocol. The MDTM command returns the modification time of the specified file on the server as a string in the format YYYYMMDDHHMMSS. We use the sendcmd() method of the FTP class to send the MDTM command to the server and retrieve the modify time of the file.
Storing the modify time in a dictionary
After retrieving the modify time of a file from the FTP server, we store it in a dictionary along with the filename. This helps us in organizing and retrieving the files based on their modification times. We can use the dictionary to create a sorted list of files based on their modification times.
Comparing the modify times of different files
We can compare the modify times of different files on the FTP server and sort them based on their modification times. This helps us in organizing and retrieving the files based on their modification times. We can use the datetime module in Python to convert the string representation of the modification time into a DateTime object and perform comparisons on them.
Table Comparison
| Method | Description | Pros | Cons |
|---|---|---|---|
| nlst() | Returns a list of filenames present on the server | Simple and easy to use | Does not provide detailed information |
| dir() | Returns the details of a specific file on the server | Provides detailed information about the file | Requires additional processing to extract relevant information |
| MDTM command | Returns the modification time of a specified file on the server | Provides accurate information about the modification time | Requires sending a separate command to the server |
Opinion
In conclusion, retrieving the modify time of files from FTP servers using Python is a simple process that can be accomplished with the help of the ftplib module. The method you choose to retrieve this information depends on your requirements and the level of detail you need. The nlst() method is simple and easy to use but does not provide detailed information about the files. The dir() method provides detailed information but requires additional processing to extract relevant information. Finally, the MDTM command provides accurate information about the modification time but requires sending a separate command to the server. Overall, any of these methods can be used depending on your specific requirements.

Python Tips: How to Retrieve FTP File’s Modify Time Using ftplib
Here are some frequently asked questions about retrieving FTP file’s modify time using ftplib:
-
What is ftplib in Python?
ftplib is a Python module that provides a way to interact with FTP servers. It allows you to write Python programs that can retrieve files from an FTP server, upload files to an FTP server, and perform other FTP-related tasks.
-
How do I retrieve the modify time of an FTP file using ftplib?
You can retrieve the modify time of an FTP file using the ftplib module’s
mdtm()method. Here’s an example:import ftplibftp = ftplib.FTP('ftp.example.com')ftp.login('username', 'password')# Retrieve the modify time of a filefilename = 'example.txt'modify_time = ftp.sendcmd('MDTM ' + filename)[4:]ftp.quit()print('The modify time of', filename, 'is', modify_time) -
What is the format of the modify time returned by mdtm()?
The modify time returned by
mdtm()is a string in the format YYYYMMDDHHMMSS. For example, 20210101120000 represents January 1st, 2021 at 12:00:00. -
Can I convert the modify time string to a datetime object?
Yes, you can use Python’s
datetime.strptime()method to convert the modify time string to a datetime object. Here’s an example:from datetime import datetimemodify_time = '20210101120000'datetime_object = datetime.strptime(modify_time, '%Y%m%d%H%M%S')print(datetime_object)
