FileGDB

Upload a zipped .gdb folder containing your geodatabase.

How to open FileGDB online

Open ESRI File Geodatabase (FileGDB). Upload a zipped .gdb folder containing your geodatabase.

Privacy

Files are processed on your device in the browser. GeoDataViewer does not upload your datasets to a server for viewing.

Common issues

If a dataset uses multiple required sidecar files, make sure you provide the complete set together. For best results, keep all sidecars in one zip archive when applicable.

Related tools

Measure distances, areas, elevation, and radius circles using the tools menu, then come back to inspect your FileGDB layer on the map.

What is FileGDB?

File Geodatabase is an Esri geodatabase storage format that organizes datasets as a folder-based database instead of a single portable file.

FileGDB is widely used in ArcGIS environments because it can hold multiple feature classes, tables, and related content inside one geodatabase directory.
That structure is powerful inside Esri workflows, but it is less convenient than single-file formats for email, versioning, web uploads, and cross-platform sharing.

What is FileGDB used for?

  • Managing multi-layer geospatial datasets in ArcGIS-centered environments.
  • Delivering richer geodatabase-style content than a flat exchange format can comfortably hold.
  • Supporting desktop GIS workflows that expect ArcGIS-native packaging and semantics.

Common use cases

  • Utility, government, environmental, and infrastructure projects built around ArcGIS desktop workflows.
  • Folder-based delivery of multiple feature classes and reference tables.
  • Intermediate storage before data is repackaged for portals, vendors, or web products.

Strengths

  • Can hold multiple layers and related tables in one geodatabase structure.
  • Strong fit for ArcGIS workflows and geodatabase-oriented data management.
  • More expressive than simple flat exchange formats when the project is multi-layer.

Limitations

  • FileGDB is a folder dataset, so it often needs zipping before transfer or browser upload.
  • Non-Esri workflows frequently prefer a more neutral or simpler delivery format.
  • The structure is less convenient for quick manual inspection than text or single-file containers.

File extensions and sidecar files

.gdb folder
Main geodatabase directory that contains tables, indexes, and supporting metadata files.
.gdbtable
Internal storage files used for tables and feature classes inside the geodatabase.
.gdbtablx
Internal index files that support geodatabase table access.
zipped .gdb folder
Common way to move a FileGDB through email, browsers, and archive systems that expect one transferable package.

FileGDB Viewer FAQ

Why is FileGDB usually shared as a zip?

The geodatabase is a folder with many internal files, so zipping it keeps the structure intact during transfer.

When should I keep data in FileGDB?

Keep it there when the primary users work in ArcGIS-style multi-layer geodatabase workflows and benefit from that structure.

Why convert FileGDB to GeoPackage or GeoJSON?

Those targets are easier to upload, share, preview in browsers, and exchange with tools outside the ArcGIS ecosystem.
