Python - How to get the latest file in a folder?

To get the latest file in a folder using Python, you can use the os module to list files and os.path.getctime to get the creation time of each file. Here's an example:

import os def get_latest_file(folder_path): # List all files in the folder all_files = os.listdir(folder_path) # Filter out directories files = [file for file in all_files if os.path.isfile(os.path.join(folder_path, file))] # Get the latest file based on creation time latest_file = max(files, key=lambda file: os.path.getctime(os.path.join(folder_path, file))) # Return the full path of the latest file return os.path.join(folder_path, latest_file) # Replace 'your_folder_path' with the actual path to your folder folder_path = 'your_folder_path' latest_file_path = get_latest_file(folder_path) print("Latest File:", latest_file_path)

Replace 'your_folder_path' with the actual path to your folder. The function get_latest_file will return the full path of the latest file in that folder based on creation time.

Note: This example uses the creation time of files. If you need to use modification time or another criterion, you can adjust the code accordingly.

Examples

  1. Get Latest File Using os.listdir and os.path.getctime:

    • "Python get latest file in folder os.listdir example"
    • Code:
      import os folder_path = '/path/to/your/folder' latest_file = max(os.listdir(folder_path), key=lambda f: os.path.getctime(os.path.join(folder_path, f)))
    • Description: Uses os.listdir to list files, and os.path.getctime to get the creation time and find the latest file.

  2. Get Latest File Using os.scandir and stat:

    • "Python get latest file in folder os.scandir example"
    • Code:
      import os from stat import S_ISREG, ST_CTIME, ST_MODE folder_path = '/path/to/your/folder' latest_file = max(os.scandir(folder_path), key=lambda entry: entry.stat().st_ctime if S_ISREG(entry.stat().st_mode) else -1)
    • Description: Utilizes os.scandir for efficient iteration and stat to get file creation time and find the latest file.

  3. Get Latest File Using glob and os.path.getctime:

    • "Python get latest file in folder glob example"
    • Code:
      import glob import os folder_path = '/path/to/your/folder' latest_file = max(glob.glob(os.path.join(folder_path, '*')), key=os.path.getctime)
    • Description: Uses glob to get a list of files and os.path.getctime to find the latest file based on creation time.

  4. Get Latest File Using os.listdir and os.path.getmtime:

    • "Python get latest file in folder os.path.getmtime example"
    • Code:
      import os folder_path = '/path/to/your/folder' latest_file = max(os.listdir(folder_path), key=lambda f: os.path.getmtime(os.path.join(folder_path, f)))
    • Description: Similar to the first example, but uses os.path.getmtime to get the modification time for finding the latest file.

  5. Get Latest File Using pathlib and stat:

    • "Python get latest file in folder pathlib example"
    • Code:
      from pathlib import Path from stat import S_ISREG, ST_CTIME, ST_MODE folder_path = Path('/path/to/your/folder') latest_file = max(folder_path.iterdir(), key=lambda entry: entry.stat().st_ctime if S_ISREG(entry.stat().st_mode) else -1)
    • Description: Utilizes the pathlib module for more modern file path handling and stat for getting file creation time.

  6. Get Latest File Using os.listdir and os.path.getmtime with os.path.join:

    • "Python get latest file in folder os.path.join example"
    • Code:
      import os folder_path = '/path/to/your/folder' latest_file = max([os.path.join(folder_path, f) for f in os.listdir(folder_path)], key=os.path.getmtime)
    • Description: Constructs the full file path using os.path.join while finding the latest file based on modification time.

  7. Get Latest File Using os.scandir and os.path.getmtime:

    • "Python get latest file in folder os.scandir getmtime example"
    • Code:
      import os folder_path = '/path/to/your/folder' latest_file = max(os.scandir(folder_path), key=lambda entry: entry.stat().st_mtime)
    • Description: Uses os.scandir and os.path.getmtime to find the latest file based on modification time.

  8. Get Latest File Using sorted and os.path.getctime:

    • "Python get latest file in folder sorted example"
    • Code:
      import os folder_path = '/path/to/your/folder' latest_file = sorted(os.listdir(folder_path), key=lambda f: os.path.getctime(os.path.join(folder_path, f)))[-1]
    • Description: Sorts the list of files by creation time and selects the last (latest) file.

  9. Get Latest File Using os.listdir and os.path.getmtime with max function:

    • "Python get latest file in folder os.listdir max example"
    • Code:
      import os folder_path = '/path/to/your/folder' latest_file = max((os.path.join(folder_path, f) for f in os.listdir(folder_path)), key=os.path.getmtime)
    • Description: Combines os.listdir and os.path.getmtime with the max function to find the latest file.

  10. Get Latest File Using os.listdir and os.path.getatime:

    • "Python get latest file in folder os.path.getatime example"
    • Code:
      import os folder_path = '/path/to/your/folder' latest_file = max(os.listdir(folder_path), key=lambda f: os.path.getatime(os.path.join(folder_path, f)))
    • Description: Finds the latest file using os.path.getatime (access time) instead of creation or modification time.
