About Local File Trigger
The Local File Trigger node in n8n watches a folder on your server’s file system and starts a workflow whenever a file is created, modified, or deleted. It turns your file system into an event source: drop a file into a watched folder and n8n automatically picks it up and processes it.
This is particularly useful for businesses that receive data as files: CSV exports from legacy systems, PDF invoices from suppliers, XML feeds from government portals, or images that need processing. Instead of someone manually checking a folder, opening each file, and entering data into another system, the Local File Trigger detects new files immediately and kicks off the processing workflow.
The node monitors a specified directory path and can filter by file extension. When it detects a change, it outputs the file path, file name, and event type (created, changed, deleted). You then use subsequent nodes (Read Binary File, Spreadsheet File, CSV, or code nodes) to read and process the file contents.
At Osher, we use the Local File Trigger in automated data processing workflows where files arrive from external systems via SFTP, shared drives, or manual uploads. A typical build watches an SFTP landing folder, picks up new CSV files, parses the data, validates it, and loads it into a database or CRM. Our RPA team uses this pattern to replace manual file-processing tasks across finance, operations, and admin teams.

How it works
We work hand-in-hand with you to implement Local File Trigger
As Local File Trigger consultants we work with you hand in hand build more efficient and effective operations. Here’s how we will work with you to automate your business and integrate Local File Trigger with integrate and automate 800+ tools.
Step 1
Process Audit
We review how files currently arrive in your business: SFTP drops, email attachments saved to folders, manual uploads, or system exports. We document the file types, formats, volumes, and what happens to each file after it arrives (who processes it, where the data goes, how long it takes).
Step 2
Identify Automation Opportunities
We identify which file-processing tasks can be automated: parsing CSV imports into a database, extracting data from PDF invoices, validating XML feeds against schemas, and routing files to different workflows based on type or content. Each task is evaluated for time savings and error reduction.
Step 3
Design Workflows
We design the n8n workflow with Local File Trigger as the entry point, followed by file reading nodes, parsing logic, validation steps, and destination actions. The design includes file type filtering, error handling for corrupt files, and post-processing steps (archiving or deleting processed files).
Step 4
Implementation
We configure the watched directory path, file extension filters, and polling interval on your self-hosted n8n instance. We build the downstream processing workflow, connect it to your target systems (database, CRM, accounting tool), and test with real files to confirm end-to-end processing works correctly.
Step 5
Quality Assurance Review
We test with various file scenarios: empty files, corrupt files, files with unexpected formatting, very large files, and simultaneous file arrivals. We verify that error handling catches problems gracefully, that processed data lands in the correct destination, and that no files are lost or processed twice.
Step 6
Support and Maintenance
We monitor the file trigger for issues like disk space problems, permission changes, and processing errors. When file formats change (new columns in a CSV, updated XML schema), we update the parsing logic. We also manage file archival and cleanup to prevent the watched folder from growing indefinitely.
