Creo Elements/Pro, also known as Pro/Engineer, was developed by PTC as a CAD/CAM application for Microsoft Windows.
The 78 file contains versioned data from Creo Elements/Pro and is associated with the software's design data.
Use Pro/Engineer or Creo Elements/Pro on Microsoft Windows to work with the associated design and its versioned data. The 78 file may be supporting data rather than a standalone document, so it might not open independently.
If the software does not recognize the file, open the related Creo design data instead of renaming the extension.
The 78 file is not a general-purpose interchange format and may not be convertible directly.
If the associated design can be opened in Pro/Engineer or Creo Elements/Pro, use that application's save or export functions to create a supported design or exchange file. This may not preserve the versioned-data information stored in the 78 file.
