ComfyUI Node: Add File Name Prefix

Add File Name Prefix:

The Add File Name Prefix node is designed to enhance file management by allowing you to prepend a specified prefix to file names within a given directory path. This node is particularly useful for organizing files systematically, ensuring that they are easily identifiable and sortable based on the prefix added. By using this node, you can streamline your workflow, especially when dealing with large volumes of files that require consistent naming conventions. The primary function of this node is to concatenate a user-defined prefix to the existing file name, thereby creating a new file path that reflects the updated naming structure. This capability is essential for maintaining order and clarity in file storage systems, making it easier to locate and manage files efficiently.

Add File Name Prefix Input Parameters:

path

The path parameter specifies the directory path where the file is located. It is crucial as it determines the location in which the file name prefix will be applied. This parameter does not have a default value and must be provided to ensure the node functions correctly. The path should be a valid directory path where the file resides.

file_name_prefix

The file_name_prefix parameter allows you to define the prefix that will be added to the file name. This parameter is a string and is essential for customizing the file naming convention. By default, this parameter is an empty string, meaning no prefix will be added unless specified. The prefix can be any string that suits your organizational needs, and it will be prepended directly to the file name.

Add File Name Prefix Output Parameters:

STRING

The output of this node is a STRING that represents the new file path with the added prefix. This output is crucial as it provides the updated path that reflects the new naming convention. The string output allows you to verify the changes made to the file name and ensures that the file can be accessed using its new path. This output is particularly useful for subsequent processes that require the updated file path.

Add File Name Prefix Usage Tips:

• Ensure that the path parameter is correctly specified to avoid errors related to file location. Double-check the directory path to ensure it is valid and accessible.
• Use meaningful and consistent prefixes in the file_name_prefix parameter to maintain an organized file structure. This practice will help in easily identifying and sorting files based on their prefixes.

Add File Name Prefix Common Errors and Solutions:

Invalid path specified

• Explanation: This error occurs when the provided path parameter does not point to a valid directory.
• Solution: Verify that the directory path is correct and accessible. Ensure that there are no typos or incorrect directory levels in the path.

Empty file name prefix

• Explanation: If the file_name_prefix is left empty, no prefix will be added to the file name.
• Solution: Specify a meaningful prefix in the file_name_prefix parameter to ensure that the file name is updated as intended.
