Information about the .gdb (gdb) file type

This is one of three possibilities that we have on file for the .gdb file extension, follow this link to view all three possibilities.

Below is all the information we have available on file about the .gdb (gdb) file type.

ESRI GeoDatabase file.

A .gdb file is an ESRI ArcGIS "geodatabase" file. The file combines spatial data (hence "geo-") with a data repository (hence "-database"), providing a data repository for spatial data.

Whilst ArcGIS treats these as files, the .gdb extension is actually applied to a folder.

The file format of .gdb files is proprietary to ESRI and not public. To access the data contained in a geodatabase (.gdb file) requires the use of one of the ESRI ArcGIS tools. The file format has changed with the release of later ArcGIS versions. In general ArcGIS can read .gis files created with earlier versions of ArcGIS, but cannot read .gis files created with later versions.

The following link provides further information related to the .gdb file extension:

Where this is available we would like to include file format information on .gdb files, as well as information on how to view or open files of type .gdb. If you know of any information which we have missed then please let us know.
