Snippet Details 📃

• Snippet Name: file_organizer.py
• Category: File_Organizer
• Function Name: organize_files_by_type

Summary of Changes

• The organize_files_by_type snippet sorts files in a specified directory into categorized subfolders like 'Images', 'Documents', and 'Videos', enhancing file organization and accessibility.
• Users must ensure the folder path exists, as the function raises a ValueError for invalid paths. Unrecognized file types will be noted, helping users identify files that weren't categorized.

Example Usage

# Example usage of the organize_files_by_type function
folder_to_organize = r"path_to_the_folder"  # Replace with the actual folder path
try:
    organize_files_by_type(folder_to_organize)
    print("Files organized successfully.")
except ValueError as e:
    print(e)

• Changes were verified by executing all tests successfully, conducting a code review and performing manual tests to confirm proper file organization.
