ComfyUI Node: 🗘 For Each Filename

For Each Filename [DVB]:

The "For Each Filename" node is designed to streamline the process of iterating over files within a specified directory that match a given pattern. This node is particularly useful for batch processing tasks where you need to apply the same operation to multiple files, such as images or videos. By automating the file selection and iteration process, it saves you time and effort, allowing you to focus on the creative aspects of your project. The node ensures that each file is processed in sequence, maintaining a state to track which files have been processed and which are yet to be handled. This functionality is essential for tasks that require consistent and orderly processing of multiple files.

For Each Filename [DVB] Input Parameters:

id

This parameter is a unique identifier for the iteration process. It helps in maintaining the state of the files being processed, ensuring that each file is handled only once. The id should be a string that uniquely identifies the current batch processing task.

directory

This parameter specifies the directory where the files to be processed are located. It should be a string representing the path to the directory. The default value is set to the input directory defined in the comfy_paths configuration. Ensure that the directory path is correctly specified and exists, as the node will check for its validity.

pattern

This parameter defines the pattern used to match the filenames within the specified directory. It should be a string representing the file pattern, such as *.jpg for JPEG images. The default value is *.jpg. This pattern helps in filtering the files that need to be processed, allowing you to target specific file types or naming conventions.

For Each Filename [DVB] Output Parameters:

filepath

This output parameter provides the full path of the current file being processed. It is a string that can be used in subsequent nodes to access or manipulate the file.

name

This output parameter gives the name of the current file without its extension. It is a string that can be useful for logging, naming outputs, or other identification purposes.

foreach

This output parameter is a state file that keeps track of the files processed and those yet to be processed. It is used internally by the node to manage the iteration process and ensure that each file is handled in sequence.

For Each Filename [DVB] Usage Tips:

• Ensure that the directory parameter points to a valid directory containing the files you want to process. Double-check the path to avoid errors.
• Use specific and appropriate patterns in the pattern parameter to filter the files accurately. For example, use *.png for PNG images or *.mp4 for MP4 videos.
• Utilize the id parameter to differentiate between multiple batch processing tasks. This helps in maintaining separate states for different tasks.

For Each Filename [DVB] Common Errors and Solutions:

Not a directory: <directory_path>

• Explanation: This error occurs when the specified directory path is not valid or does not exist.
• Solution: Verify that the directory parameter is correctly set to a valid directory path. Ensure that the directory exists and is accessible.

No more files to process.

• Explanation: This error indicates that there are no more files matching the specified pattern in the directory to be processed.
• Solution: Check the pattern parameter to ensure it correctly matches the files you intend to process. Also, verify that the directory contains files that match the pattern.
