AutoFileStorer & AutoFileStorerExplorer Nodes

Overview

The AutoFileStorer and AutoFileStorerExplorer nodes work together to store and explore files within a specified directory in an n8n workflow.

• AutoFileStorer: Stores uploaded files to the disk and can optionally hash filenames for uniqueness.
• AutoFileStorerExplorer: Lists files in a directory with detailed metadata such as MIME type, size, and last modified date.

Features

• File Storage: Save uploaded files to a specified directory, with optional hashing for unique filenames.
• File Exploration: List stored files and return metadata such as file name, path, MIME type, size, and last modified date.
• Metadata Support: Provides file details for effective file management in workflows.

Node Properties

AutoFileStorer

• Directory Path: Specify where to store the files (default is ./n8n_storage/uploaded_files).
• Hash Filenames: Option to hash filenames using MD5 to ensure uniqueness.

AutoFileStorerExplorer

• Directory Path: Specify the directory to explore (default from config or ./n8n_storage/uploaded_files).

Inputs/Outputs

AutoFileStorer Outputs

Stores files in the specified directory and outputs metadata, including:

• fileName: The name of the file.
• filePath: The path where the file is stored.
• fileOriginName: The original file name before storage.

AutoFileStorerExplorer Outputs

Lists files and their metadata:

• fileName: The name of the file.
• filePath: The full path to the file.
• fileMimeType: The MIME type of the file.
• fileSize: The size of the file in bytes.
• lastModifiedDate: The date the file was last modified.

Warnings

• File Overwriting (AutoFileStorer): Files will be overwritten if not hashed (if the same file already exists).
• File Duplication (AutoFileStorer): Files with hashed names may result in duplicates if uploaded multiple times (if the same file is uploaded multiple times).
• Directory Access (AutoFileStorerExplorer): Ensure n8n has read permissions to the directory.

Error Handling

• Invalid Path: If the directory doesn't exist or isn't accessible, an error will be thrown.
• Permission Denied: Ensure proper file permissions for reading and writing to the directory.

Conclusion

The AutoFileStorer and AutoFileStorerExplorer nodes provide a simple and effective way to manage file uploads and file exploration in n8n workflows, offering flexibility with file handling and retrieval.
