File Explorer

The File Explorer provides a streamlined interface to browse, preview, and open files in cloud object storage and the mounted disk. Fused supports Amazon S3 and Google Cloud Storage, with more integrations coming soon.

When working with data, it can be time-consuming to track down datasets, request access, download gigabytes of data, and write boilerplate code to read files. The File Explorer simplifies this process by enabling users to easily browse any object storage bucket, visualize file contents without writing code, and quickly create User Defined Functions (UDFs) in the UDF Builder with templates for specific file types.

Browse​

Browse directories and files in buckets. Use the search bar and filter options to quickly locate specific files, and "Favorite" files for quick access. To explore a bucket, find it in the "Favorites" dropdown or paste its path. To connect private buckets, contact Fused.

Preview​

The Explorer displays a bucket's directories and objects as folders. Each listed file shows metadata such as file size and path, along with utilities to download or delete the file, copy its path, generate a signed URL, and create a UDF to open it.

Click on a file to preview its content. If the file has a spatial component, it will be displayed on the map, allowing you to zoom and pan to explore the rendered data. For images or other file types, Fused will make a best-effort to render and display the content.

Create UDF​

Create Fused UDFs using templates for common file types. Double-click on a file to create a new templated UDF that reads the file, or find additional readers in the file's kebab menu. Parquet tables show an "Open Table" button to open them at the directory level.

Template UDFs​

Template UDFs are available for common file types (like CSV, Parquet) and tools (like DuckDB and GeoPandas). See the latest template UDFs in the UDFs repo.

Supported file types for vector tables include parquet, JSON, CSV, excel, zip, and KML. For raster files GeoTIFF and NetCDF are supported. If you need a file type that isn't supported, request it on the Fused Discord channel or contribute a template to the community.

Upload / Download / Edit​

File Explorer also allows you to:

  • Upload files (drag & drop)
  • Download files
  • Create new directories
Directories cannot be empty

In File Explorer directories will not be saved if they do not have content in them.

Connect your own bucket​

Professional and Enterprise This feature is accessible to organizations with a Fused Professional & Enterprise subscription.

Connect S3 or GCS buckets to access their files interactively from within the File Explorer UI and programmatically from within UDFs. Contact Fused to set a bucket on the File Explorer for all users in your organization, or set a bucket as a "favorite" so it appears for your account only.
