ComfyUI Node: get file list

get file list:

The io-util-file-list-get node is designed to help you retrieve a list of files from a specified directory that match a given pattern. This node is particularly useful for organizing and managing files, especially when you need to process or analyze multiple files at once. By specifying a directory and a pattern, you can easily filter and obtain the filenames or their absolute paths, depending on your needs. This functionality is essential for tasks that involve batch processing of files, such as reading multiple text files, processing images, or any other file-based operations. The node simplifies the process of file retrieval, making it more efficient and less error-prone.

get file list Input Parameters:

path

The path parameter specifies the directory from which you want to retrieve the files. It is a string input where you provide the path to the directory. The default value is an empty string, which means you need to specify the directory path for the node to function correctly. This parameter is crucial as it determines the location from which the files will be listed.

pattern

The pattern parameter allows you to define the type of files you want to retrieve from the specified directory. It is a string input where you can use wildcard characters to match specific file types. The default value is *.txt, which means it will list all text files in the directory. You can change this pattern to match other file types, such as *.jpg for images or *.csv for CSV files. This parameter helps in filtering the files based on their extensions or naming patterns.

mode

The mode parameter determines how the file paths will be returned. It offers two options: filename and abspath. If you choose filename, the node will return only the names of the files. If you choose abspath, it will return the absolute paths of the files. This parameter is important as it allows you to control the format of the output based on your specific requirements. The default value is filename.

get file list Output Parameters:

STRING

The output parameter STRING contains the list of files that match the specified pattern in the given directory. The files are returned as a single string, with each filename or absolute path separated by a newline character. This output is useful for further processing or analysis, as it provides a consolidated list of the files that meet your criteria.

get file list Usage Tips:

• Ensure that the path parameter is correctly specified to avoid errors in file retrieval.
• Use appropriate wildcard patterns in the pattern parameter to filter the files you need.
• Choose the mode parameter based on whether you need just the filenames or the full paths of the files.

get file list Common Errors and Solutions:

Directory not found

• Explanation: The specified directory in the path parameter does not exist.
• Solution: Verify that the directory path is correct and that it exists on your file system.

No files match the pattern

• Explanation: The pattern specified in the pattern parameter does not match any files in the directory.
• Solution: Check the pattern for any typos and ensure it correctly matches the file types you are looking for.

Permission denied

• Explanation: The node does not have permission to access the specified directory.
• Solution: Ensure that you have the necessary permissions to read the directory and its contents. Adjust the permissions if necessary.
