GDB format

Hi Alexander,

Regarding the GDB format can you verify this code:

Console.WriteLine(" Gdb:");
** Console.WriteLine(" Purpose:a folder-based database format from Esri storing multiple feature classes and tables.“);**
** Console.WriteLine(” Files needed: FileGdb can be represent as a dataset or just as one table.“);**
** Console.WriteLine(” In case of dataset - the entire .gdb folder as a single file.“);**
** Console.WriteLine(” In case of one table - .gdbtable and .gdbtablx as an archive file.");**
** Console.WriteLine();**

General:

Structure of a File Geodatabase (.gdb)

  • A .gdb appears as a folder on your computer. Inside, there are many files with different extensions (e.g., .gdbtable, .gdbtablx, .gdbindexes), but you never interact with them directly—ArcGIS handles them internally.
  • The user-visible “mandatory” part is simply the folder itself with the .gdb extension.

Mandatory component

  • The folder ending in .gdb
    • Without the folder, there’s no geodatabase.
    • Everything inside is managed by ArcGIS; you don’t need to worry about individual internal files.

Optional or internal files

  • .gdbtable, .gdbtablx, .gdbindexes, .gdbp, etc.
    • These are created automatically by ArcGIS for storing feature classes, tables, spatial indexes, etc.
    • You don’t manually create them.

Thanks in advance,

• Is the user seeking verification of the technical accuracy of the GDB format description provided?

• Does the user need clarification on whether FileGDB can indeed be represented as either a dataset folder or individual table files?

• Are there specific concerns about the file extensions mentioned (.gdbtable, .gdbtablx, .gdbindexes) and their relationship to the overall GDB structure?

• Should the user be informed about the difference between a File Geodatabase folder and its internal file components?

• Is the user requesting confirmation that ArcGIS manages all internal GDB files automatically without manual intervention?

• Would the user benefit from understanding the distinction between mandatory folder structure and optional internal files?

Hi Alexander,
Can you please answer?
Thanks,

Hi, @danies8
Yes, this is correct.

OK.
For both inputs: the entire .gdb folder as a single file or .gdbtable and .gdbtablx as an archive file.
What are the mandatories files: .gdbtable and .gdbtablx
Your quick answer will be appreciated.
Thanks,

Hi Alexander,
1.For both inputs:
The entire .gdb folder as a single file or .gdbtable and .gdbtablx as an archive file .
What are the mandatories files: .gdbtable and .gdbtablx ?

  1. In case of .gdbtable and .gdbtablx as an archive file , what should be extension of archive file ?
    It should be . gdb or an archive suffix like .zip .7z …?

Your quick answer will be appreciated.

Hi, @danies8
yes, gdbtable and gdbtablx

It’s up to you. In your code you use archive file! For our API to use VectorLayer.Convert you need to set path to gdbtable.

Can i set in your api Path to .gdb folder also?
Or i need to find the .gdbtable file from gdb and verify that also gdtablx exists there?

Your quick answer will be appreciated.

Yes, you can. In case of dataset
