If not all ArcGIS tools support both foreground and background Geoprocessing, then how can I tell whether a tool will run in the foreground or run in the background?

    Your question is too broad because it contains three questions when the Tour stipulates that there should be only one question per question. – PolyGeo Dec 30 '15 at 8:06
  • but all these questions are related. So should be asked in one question. – Ahsan Mukhtar Dec 30 '15 at 11:57

    You shold assume that all GP tools will run in the background unless the "run in background" Geoprocessing option is disabled. This question is far too broad, since there are hundreds of tools, and dabbles in opinion-based as well, since "why was it coded this way" questions aren't likely to attract definitive answers. – Vince Dec 30 '15 at 12:08

The tools that do not run in the background are listed on the help page entitled Background Geoprocessing (64-bit):

Tools that do not run in the background include the following:

  • Tools inside the Metadata conversion toolset
  • Tools inside the Geodatabase administration toolset
  • All Coverage tools
  • Tools which create packages
  • Graphing tools (64-bit geoprocessing only; these tools work in traditional 32-bit background processing)
  • Custom script, model, or function tools where the author has disabled background processing


Any script or script tools you run while inside Desktop honors the background processing setting.

I encourage you to visit the help page for more information.
