What is a GBP file?
A .GBP file is most commonly a Gerber Bottom Solder Paste Data File. Engineers and designers use CAD software like Altium Designer to export these files. A .GBP file contains 2D vector instructions that tell manufacturing machines exactly where to apply solder paste on the bottom layer of a printed circuit board (PCB). The standard Gerber format is globally maintained by Ucamco.
Because file extensions are not strictly regulated, a .GBP file can also be a completely different format. For example, Genie Backup Manager creates .GBP files as backup archives, which often rely on standard ZIP compression under the hood. Furthermore, the disk authoring software gBurner uses the .GBP extension to save user project settings.
How to open GBP files?
If you know your file contains PCB manufacturing data, you can open it with specialized viewing software like GerbV or an open-source EDA suite like KiCad. If the file is a system backup, you will need Genie Backup Manager. Since Genie backups are often standard archives, you can sometimes extract them using command-line tools or archivers like 7-Zip, provided the file is not encrypted.
Online Inspection and Analysis
Because .GBP has multiple possible meanings, we recommend using viewer.online/gbp to identify the actual format of your file. Our tool can analyze .GBP files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Summary
viewer.online/gbp is useful for identifying, inspecting, and understanding .GBP files without installing software or dealing with compatibility problems.
