The file is saved in FreeCAD Standard format which uses ZIP compression. Various kinds of CAD data as a series of files compressed into a single FCSTD file. FreeCAD is able to organize and distinguish the contents of an FCSTD container (file) by referring to the container's Document.xml or GuiDocument.xml file which describes all object/property definitions. Other contents of an FCSTD file include a 128 x 128 pixels thumbnail, object shapes (BREP/BRP), and 2D technical drawings (SVG) generated from 3D models.

4 Steps to Open an Unknown .FCSTD File
Because .FCSTD files may come from different programs, they aren't universally openable.
- Identify the Source: Files received from an engineer or 3D designer strongly suggest a CAD model or drawing.
- Check the Header: Inspect the first bytes in a text or hex editor:
- "PK" indicates a ZIP archive (FreeCAD files are actually zipped XMLs).
- Readable XML implies a plain-text data file.
- Use the Original Software: You usually need the original program to open it; try FreeCAD, a compatible CAD viewer, or ask the sender.
- Use this Webpage: Drag and drop your file onto this page to detect its format, extract metadata, and preview contents.
