Have you ever wondered how to connect to a remote server using Python and list all the folders and files that are located there? Well, in this article, I’m going to share with you how to establish an SFTP connection and retrieve all the data using Python coding.
If you’re someone who works with servers and file transfer, then you probably already know that Secure File Transfer Protocol or SFTP is a secure way of transferring files in a network. Python, on the other hand, is a programming language that is widely used for various applications including web development, scientific calculations, and data analysis.
With Python’s Paramiko library, you can establish an SFTP connection and easily list all the folders and files present in the remote server. Whether you want to automate file processing or just need to read data from a remote location, this method will be useful as it saves your time and effort in transferring the data manually.
So, if you’re interested in connecting to a remote server via Python and retrieving all the available folders and files, then keep reading and follow the step-by-step guide provided below. It’s going to be easy and fun, especially if you’re someone who loves working with Python and automation.

Comparison Blog Article: Python SFTP Connection – Listing All Folders and Files
Introduction
Many developers often have to deal with remote file transfers, whether it be uploading files, downloading files or simply listing all the files and folders on a remote server. Python has an excellent library called Paramiko which provides an easy way to establish an SFTP connection and accomplish these tasks. In this article, we will compare two different approaches to listing all files and folders through an SFTP connection using Python.
Approach 1: Using Paramiko’s .listdir() Method
The first approach involves simply using the listdir() method provided by the SFTPClient class in the Paramiko library. This method returns a list of all directories and files present in the current remote directory.
Code Implementation
Here is what the code implementation would look like:
“`import paramikossh = paramiko.SSHClient()ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())ssh.connect(hostname, username=username, password=password)sftp = ssh.open_sftp()listing = sftp.listdir()for file in listing: print(file)sftp.close()ssh.close()“`
Table Comparison
| Pros | Cons ||————–|——————||Simple and easy to implement.|Not very efficient in terms of performance if there’s a large number of files/directories.||Doesn’t require additional libraries.|Only lists files/folders from the current directory.||Suitable for simple use-cases.|May not be suitable for more complex requirements such as filtering out certain types of files, sorting files in a particular order or listing hidden files.|
Opinion
The first approach is definitely the simplest and easiest to implement, but it may not be suitable for all use-cases. If you’re just looking to get a quick list of files and directories in the current directory then this approach would be sufficient, but if you have more complex requirements then you may need to look into other solutions.
Approach 2: Using os.walk() Method
The second approach involves using the os.walk() method which is a generic function in the Python standard library that allows you to traverse the file system and returns tuples containing information about the directories, sub-directories and files being traversed. We can leverage this function to get a list of all files and folders in the remote system.
Code Implementation
The code implementation would look like:
“`import paramikossh = paramiko.SSHClient()ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())ssh.connect(hostname, username=username, password=password)sftp = ssh.open_sftp()for root, dirs, files in sftp.walk(‘/’): for name in files: print(os.path.join(root,name)) for name in dirs: print(os.path.join(root,name))sftp.close()ssh.close()“`
Table Comparison
| Pros | Cons ||————–|——————||Can be used for complex requirements such as filtering out certain types of files, sorting files in a particular order or listing hidden files.|Requires the os module and additional code logic.||More efficient than using Paramiko’s .listdir() method when there are a large number of files/directories.|Can be more difficult to implement for beginners.||Lists all files/folders in the remote system.|Takes a bit more time to run than Paramiko’s .listdir() method.|
Opinion
If you have more complex requirements or there are a large number of files and directories, then the second approach using os.walk() would be more suitable. However, this approach requires additional code and therefore may not be as easy to implement compared to the simpler solution provided by the listdir() method.
Conclusion
Both of these approaches allow us to list all files and folders in a remote server using Python’s SFTP connection through the Paramiko library. The listdir() method is simple and easy to implement but may not be suitable for complex use-cases or performance-intensive tasks. The os.walk() method, on the other hand, provides more flexibility and faster performance but may be more challenging to implement. Ultimately, the best approach will depend on your specific requirements and use-case.

People also ask about Python SFTP Connection: Listing All Folders and Files:
- How do I connect to SFTP using Python?
- To connect to SFTP using Python, you can use the paramiko module. First, create a client object and set the hostname, port, username, and password. Then, open the SSH transport and authenticate the client. Finally, use the SFTP protocol to manipulate files.
- To list all folders and files in SFTP using Python, you can use the listdir() method of the SFTPClient class. First, create an SFTP client object and connect to the server. Then, use the listdir() method to get a list of all entries in the remote directory. Finally, iterate over the list and print the name of each entry.
- To filter files in SFTP using Python, you can use the fnmatch module. First, import the fnmatch module. Then, use the listdir() method to get a list of all entries in the remote directory. Finally, use a list comprehension to filter the entries based on a pattern using the fnmatch.filter() method.
