What is a BOT file?

BOT files mostly belong to OrCAD PCB Designer. BOT files serve several distinct purposes. The primary use is in printed circuit board (PCB) design. In this context, a BOT file is a Gerber Bottom Layer File that contains vector instructions for etching the copper on the bottom side of a PCB. These files are produced by software like OrCAD PCB Designer and Altium Designer and are used along with other Gerber files to fully define a board's layout.
Use cases include:

PCB Design: The file details the bottom layer’s copper traces, pads, and holes. It provides precise instructions for manufacturing equipment.

Binary Update: In some cases, BOT stands for a Binary Object File used by tools like CFGTool to update firmware or software components.

Robot Data: Certain BOT files contain configuration data for game robots, as seen with Robot Arena 2.

FilExt.com note: These files are not images but command sets for specific machines. For more details on PCB tools, visit Cadence or Altium.

How can I open a BOT file?

You need a suitable software like OrCAD PCB Designer to open a BOT 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 BOT file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a BOT file directly in the browser:. Just drag the file onto this browser window and drop it.

BOT file format details:

The file format determines how the data is stored in the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our evaluation of the BOT files looks like this:

The BOT file extension is used very often and has no uniform or dominant file format. The file formats most commonly found in BOT files are:

• 6% of all BOT files have the same signature * G. These files are text files and can therefore be read using a text editor. The average file size is 160 KB with most files being between 8 KB and 590 KB in size. Several words can almost always be found in the files, e.g. G04 Image ***, G04 Mass Parameters ***, %MOIN*%, %ICAS*%, %IPPOS*%, %ASAXBY*%, G74*%FSLAN2X34Y34*% and G04 Aperture Definitions ***.
• 2% of all BOT files start with the bytes G04, which are crucial for this file format. The contents of these files are easily readable with a text editor. The files are on average 18 KB in size and range from 2 KB to 230 KB. Certain words are almost always found in the files, such as File and Version.

All other BOT files (92%) have no consistent format, the following 3 formats exist: EBVer. The category is adminsectex, sectex, admin, docx, xlsx or protonmail. Drag & drop your file here to see the file format and a preview of your BOT file!
