What is an FPC file?
An .FPC file is primarily a Floor Plan Project file. It stores architectural room layouts, wall dimensions, and furniture placements. The Floorplanner web application and the Floor Plan Creator mobile app commonly use this format to save and load 2D and 3D floor plan designs.
Because file extensions can overlap, an .FPC file might also be a FreePCB Printed Circuit Board Layout file. Software developer Allan Wright created the open-source FreePCB program to design electronic circuit boards, and it uses the .FPC extension to store the layout data.
How to open FPC files?
If your .FPC file is a floor plan, you can open it by uploading it to the Floorplanner platform or by importing it into the Floor Plan Creator app. If your file is an electronic design, you must use the Windows-based FreePCB software to view and edit the circuit board layout.
Because .FPC has multiple possible meanings, you can use viewer.online/fpc to analyze .FPC files to identify the exact format and creator software. The tool allows you to inspect the file structure, extract readable text, and check whether an online preview is available.
Best practices and conversions
Do not rename the .FPC extension to force it to open in other programs. This will not change the internal file format and may corrupt the data. Instead, use the native software to export the design. For example, Floorplanner can export layouts to standard image formats.
We recommend file conversion to sensible target formats on convert.guru. Depending on the original software, you might be able to convert an .FPC layout into a .PDF, .PNG, or .DWG file.
Summary
An .FPC file stores either a floor plan layout or a printed circuit board design. The viewer.online/fpc tool is useful for identifying, inspecting, and understanding .FPC files without installing software or dealing with compatibility problems.
