Zwiron includes built-in file storage so you can upload flat files and use them as pipeline sources — without needing a separate S3 bucket or file server.
File storage is included on paid plans. Start with the 14-day free trial, then subscribe to Individual or talk to us for Enterprise.

​
Zwiron-managed storage

Go to Files in the main navigation to access Zwiron’s built-in file storage.

​
Supported formats

Maximum file size: 1 GB per file.

​
Organizing files

  • Create folders to organize files by project, team, or pipeline
  • Upload files individually or in bulk
  • Files are stored with the organization and accessible to all members

​
Preview and download

  • Click any file to preview the first N rows (schema + sample data)
  • Click Download to export the file

​
Using a file as a pipeline source

To use a file you’ve uploaded as the source for an ETL pipeline:
  1. Create a new connection with connector type File (Zwiron Storage)
  2. Select the file or folder you want to use
  3. Use this connection as the source in a new job
When the job runs, Zwiron reads the file, applies any configured transforms, and writes to the destination.

​
Remote file browser

In addition to Zwiron-managed storage, you can connect to your own cloud storage and browse it directly from Zwiron. When you create a connection using:
  • Amazon S3
  • Google Cloud Storage
  • Azure Blob Storage
  • MinIO
  • SFTP
…the connection’s detail page includes a File Browser — a UI to navigate your bucket or server, browse folders, preview files, and select specific files or prefixes for a pipeline. This is useful when your files are already in cloud storage and you don’t want to re-upload them.

​
Format options

When reading a file source, you can configure:

​
File sources and scheduling

You can schedule a pipeline that reads from a file on a recurring basis. If you replace the file with a newer version (same name), the next scheduled run will read the new file automatically. This is a common pattern for daily data deliveries from partners or vendors — they drop a new CSV in an agreed folder each morning, and Zwiron picks it up automatically.
