Read/Write Files from Disk
The Read/Write Files from Disk node gives your n8n workflows direct access to the server file system. It reads files into your workflow for processing and writes output files back to disk — handling everything from CSVs and JSON files to images, PDFs, and binary data. If your automation needs to pick up files from a directory, transform them, and save the results somewhere, this is the node that makes it happen.
For businesses running self-hosted n8n instances, this node unlocks a whole category of automations that cloud-only platforms struggle with. Process invoices dropped into a shared folder, read configuration files that control workflow behaviour, generate reports and save them to a network drive, or create backup copies of important data. The node works with any file type and supports both reading single files and scanning entire directories.
Australian companies managing automated data processing pipelines find this node essential for bridging the gap between file-based systems and API-driven workflows. Many legacy systems — accounting software, inventory management, government reporting tools — still rely on file exports and imports. This node lets n8n sit in the middle, reading those exports, transforming the data, and writing it back in the format the next system expects.
The node is also valuable for AI development workflows where you need to read training data, save model outputs, or log results to disk for later analysis. Combined with n8n’s scheduling capabilities, you can build fully automated file processing pipelines that run on a timer without any manual intervention.
