ComfyUI Node: Add Filename Prefix

Add Filename Prefix [RvTools]:

The Add Filename Prefix [RvTools] node is designed to enhance file management by allowing you to prepend a specified prefix to filenames within a given directory path. This node is particularly useful for organizing and categorizing files systematically, making it easier to identify and retrieve them later. By offering the option to include date and time stamps as either a prefix or postfix, it provides a flexible way to ensure filenames are unique and informative. This feature is especially beneficial for workflows that involve generating or processing multiple files, as it helps maintain a clear and consistent naming convention.

Add Filename Prefix [RvTools] Input Parameters:

This parameter allows you to define the prefix that will be added to the filenames. It is a required string input, with a default value of "image". This prefix helps in categorizing or identifying files based on their content or purpose.

add_date_time

This parameter determines whether a date and time stamp should be added to the filename and if so, whether it should be a prefix or postfix. The options are "disable", "prefix", and "postfix". This choice allows for additional customization of the filename, making it easier to track when files were created or modified.

date_time_format

This parameter specifies the format of the date and time stamp to be added to the filename. It is a string input with a default format of "%Y-%m-%d_%H:%M:%S". This format can be customized to suit your specific needs, ensuring that the date and time information is presented in a way that is most useful for your workflow.
