.G4 File

The g4 file extension is associated with Microsoft Access, a database management system, part of Microsoft Office Suite, developed by Microsoft Corporation.

These g4 files were used by some earlier version of Microsoft Access for image files. Probably similar to TIFF format.

This g4 file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
