All about VNC Files

The VNC file type is primarily associated with GibbsCAM.

VNC	File extension: VNC
	File type:	hybrid data file

What is a VNC file?

VNC files mostly belong to GibbsCAM. VNC files can mean two different things. Some of these files are GibbsCAM CNC part files. They store data used in computer numerical control (CNC) operations. This data may include part geometry and tool path instructions used in machine work. You can open these files with GibbsCAM software.
Other VNC files are VNC connection configuration files. They contain settings for remote desktop connections using Virtual Network Computing. These files keep data like IP addresses, ports, and display settings. They work with VNC viewer applications such as those from RealVNC.
Key points as outlined by FilExt.com:

CNC use: Stores machining data for automated production.

Remote desktop use: Holds network and session settings for VNC connections.

FilExt.com note: Before opening a VNC file, verify its origin to choose the correct software. Sometimes, you can inspect the file using a text editor to check if it contains configuration details.

How to open a VNC file

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

Programs that open and convert VNC files:

GibbsCAM
See the previous paragraphs to learn more about the main application. VNC files are often referred to as GibbsCAM cads because this type of file is primarily created or used by this software.
GibbsCAM (CAD/CAM File) by Gibbs and Associates, Inc.
CAD/CAM File, with part geometry, material, tooling, feeds and speeds, workplanes, layers. Non-compatible with DXF, but can Import DXF's. This file format is classified as CAD/CAM.
TightVNC (Configuration File) by TightVNC Development Team
TightVNC is a free remote control software package derived from the popular VNC software. With TightVNC, you can see the desktop of a remote machine and control it with your local mouse and keyboard, just like you would do it sitting in the front of that computer. Program ID is VncViewer.Config
Virtual Network Computing
Virtual PC (Virtual Network Configuration File) by Microsoft Corporation
Virtual PC allows you to maintain the compatibility of legacy and custom applications during migration to new operating systems and increases the efficiency of support, development, and training staffs. Connectix Virtual PC was taken over by Microsoft and is the basis for the Microsoft product.

VNC format details:

A file format defines how the data in the file is structured. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). However, different programs can use the same file extension, and file extensions can be assigned incorrectly. So you need a detailed analysis of a file to find out the format and the associated program. In the following you will find our evaluation of the VNC files:

VNC is not a commonly used file extension and covers different formats for different programs. But the following two file formats are common:

45% of all VNC files have the same signature RFIL. These files contain neither text nor words, but only data. The file size is in the range of 62 KB to 6 MB. The file type was created 20 years ago but is still used today. The files contain the following words: RFIL, <AMData, AMgr.Table, stuff= "0">, version= "1", displayMode= "0" and <itemArray eType= "2" readOnly= "true" fmgrAvail= "false" tableName= ":Attr-Color:1" fromTableName= "UserCOLOR" name= ".
40% of all VNC files use the popular config file format. A configuration file is used by computer software to store settings. It consists of a text-based content with a structure and syntax comprising key–value pairs for properties, and sections that organize the properties. The contents of these files can even be read by a human. The average file size is 360 bytes with most files being between 330 bytes and 970 bytes in size. Several words can almost always be found in the files, e.g. [connection], host, [options], use_encoding_1=1, port=5900, password, copyrect=1, belldeiconify=0, fullscreen=0, shared=1, 8bit=0, disableclipboard=0 and viewonly=0. The file name 192.168.142.133-5900.vnc is typical for these files.

All other VNC files (15%) have different formats, frequently e.g. Conn. Tagged as desktop or cores. If you want to find out what your VNC file contains, drag and drop it onto this page.

a vnc hybrid data file is a special file format and should only be edited and saved with the appropriate software.

How to solve problems with VNC files

Associate the VNC file extension with the correct application.
Update your software that should actually open hybrid data files. Because only the current version supports the latest VNC file format. Search, therefore, e.g. on the manufacturer website after an available GibbsCAM update.
To make sure that your VNC file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
