About GBT files
The .gbt extension represents a collision of three distinct worlds: enterprise Customer Relationship Management (CRM), electronics manufacturing, and tax compliance.
GEDYS IntraWare CRM (45%): Most commonly, this is a Groupware Business Template or data object used by GEDYS IntraWare. Built on the HCL Domino (formerly Lotus Notes) architecture, these files encapsulate CRM workflows, customer records, or document templates. The Friction: These are proprietary, binary containers. You cannot double-click to open them in Word or Excel. Without the host CRM software, they are effectively "black boxes."
Gerber PCB Data (5%): In the electronics industry, a .gbt file is often a non-standard naming convention for a Gerber layer (specifically a Top or Bottom copper layer) conforming to the Ucamco RS-274X standard. The Trick: Unlike the CRM files, these are often plain ASCII text. Users frequently fail to open them simply because their CAD software expects a GBR extension.
Genius Infotank (18%): A data storage format for specialized tax software, often containing encrypted or binary-encoded fiscal reports.
Conversion Strategy:
For GEDYS: The only reliable conversion path is Export. Open the file within the GEDYS CRM client and choose File > Export to save data as CSV (for spreadsheets) or PDF (for archiving).
For Gerber: Try opening the file in a text editor like Notepad++. If the text is readable and contains codes like G04 or %FS, simply rename the extension from .gbt to .gbr. It can then be opened in standard viewers like KiCad or Altium Designer.
