What is an FCSTD1 file

FCSTD1 files mostly belong to FreeCAD. An FCSTD1 file is the FreeCAD format used for storing 3D model designs. It is a compressed file (using ZIP) that bundles all elements of a CAD project.
Inside the file, you may find:

Geometry data that defines the 3D shapes

Parametric information capturing the design history

Configuration and view settings

FilExt.com notes: This structure lets you revisit and modify design steps. Use FreeCAD to open, edit, or share the file. More details are available on the FreeCAD website.

How to open an FCSTD1 file

You need a suitable software like FreeCAD to open an FCSTD1 file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your FCSTD1 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a FCSTD1 file directly in the browser:. Just drag the file onto this browser window and drop it.

FreeCAD
See the previous paragraphs to learn more about the main application. FCSTD1 files are often referred to as FreeCAD cads because this type of file is primarily created or used by this software.
FreeCAD
A *.FCSTD1 file is a compressed archive, specifically a ZIP archive, containing the data for a 3D model created using FreeCAD. It's the primary file format for FreeCAD version 1, hence the .FCSTD1 extension. Inside the archive are various files and folders structuring the model data, including geometry, sketches, parameters, and other elements that constitute the 3D design. FreeCAD is an open-source parametric 3D modeler, and the *.FCSTD1 format reflects this parametric nature, storing not just the resulting geometry but also the design history and relationships between features. This allows for design modifications by altering original parameters, automatically updating the model accordingly. The format is designed for flexibility, enabling complex model creation and modification within the FreeCAD environment. This file format is classified as 3D Model File.

How to solve problems with FCSTD1 files

Associate the FCSTD1 file extension with the correct application.
Update your software that should actually open cad files. Because only the current version supports the latest FCSTD1 file format. Search, therefore, e.g. on the manufacturer website after an available FreeCAD update.
To make sure that your FCSTD1 file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
