ComfyUI Node: RunningHub File Saver

RunningHub File Saver:

The RunningHubFileSaver node is designed to facilitate the downloading and saving of files from specified URLs, making it a valuable tool for AI artists who need to manage and organize digital assets efficiently. This node automates the process of fetching files from the internet, determining their appropriate file types, and storing them in a user-defined directory. It supports a variety of file formats, including images and text files, and can automatically detect and assign file extensions based on the content type. Additionally, it provides a preview of image files, which can be useful for quick visual verification. The node is robust, handling errors gracefully and ensuring that files are saved correctly, even in the face of network or file system issues. By streamlining the file-saving process, the RunningHubFileSaver node helps users maintain a well-organized digital workspace, allowing them to focus more on their creative tasks.

RunningHub File Saver Input Parameters:

file_urls

This parameter is a list of URLs from which the files will be downloaded. Each URL should point to a valid file that you wish to save. The node will attempt to download each file in the list, skipping any empty or invalid URLs. There is no explicit minimum or maximum number of URLs, but the list should be manageable to ensure efficient processing.

directory

The directory parameter specifies the location on your local file system where the downloaded files will be saved. If the directory does not exist, the node will create it. This parameter is crucial for organizing your files and ensuring they are stored in a designated location.

filename_prefix

This parameter allows you to specify a prefix for the filenames of the saved files. It is useful for categorizing or identifying files based on their source or content. The prefix will be prepended to the generated filename, which can help in maintaining a structured file naming convention.

filename_delimiter

The filename_delimiter is used to separate different parts of the filename, such as the prefix and the file number. It helps in creating a readable and organized filename structure. Common delimiters include underscores or hyphens.

filename_number_padding

This parameter determines the number of digits used for numbering the files. For example, a padding of 3 would result in filenames like 001, 002, etc. This is useful for ensuring that files are sorted correctly when viewed in a file manager.

file_extension

The file_extension parameter specifies the desired file extension for the saved files. If set to "auto", the node will attempt to determine the correct extension based on the file's content type. This feature is particularly useful when dealing with various file types, as it ensures that files are saved with the appropriate extension.

open_output_directory

This boolean parameter, when set to true, will automatically open the directory containing the saved files once the operation is complete. It provides a convenient way to quickly access and review the downloaded files.

RunningHub File Saver Output Parameters:

output_paths

This output parameter is a JSON-encoded list of file paths where the downloaded files have been saved. It provides a comprehensive record of all files processed by the node, allowing you to easily locate and manage them.

combined_preview

The combined_preview is a tensor that provides a visual representation of the downloaded image files. If multiple images are downloaded, they are concatenated into a single preview. This output is particularly useful for quickly verifying the content of image files without opening each one individually.

file_types

This output parameter is a JSON-encoded list of file types corresponding to the downloaded files. It helps in understanding the nature of the files saved and can be used for further processing or categorization.

RunningHub File Saver Usage Tips:

• Ensure that the file_urls list contains valid and accessible URLs to avoid download errors.
• Use a consistent filename_prefix and filename_delimiter to maintain an organized file naming system.
• Set file_extension to "auto" to let the node automatically determine the correct extension, especially when dealing with diverse file types.
• Enable open_output_directory to quickly access and verify the downloaded files after the operation.

RunningHub File Saver Common Errors and Solutions:

Error downloading file: <error_message>

• Explanation: This error occurs when there is an issue with accessing the file at the specified URL, possibly due to network issues or an invalid URL.
• Solution: Check the URL for correctness and ensure that your internet connection is stable. Retry the operation after verifying these factors.

Error saving file: <error_message>

• Explanation: This error indicates a problem with writing the file to the specified directory, which could be due to permission issues or insufficient disk space.
• Solution: Ensure that the directory path is correct and that you have the necessary permissions to write to it. Also, check that there is enough disk space available.

Unexpected error: <error_message>

• Explanation: An unexpected error suggests that an unforeseen issue has occurred during the file-saving process.
• Solution: Review the error message for clues and check the node's configuration and input parameters for any anomalies. If the issue persists, consider seeking support or consulting the documentation for further assistance.
