What is DWG file?

The file type .DWG refers to AutoCAD Drawing Database file types. These file store all the data created by the AutoCad software in a database format. Mostly these database files contain digital data of the 2D and 3D images rendered in the AutoCAD software. There have been incremental improvements in the file format over the years from AutoCAD.

The file format is designed in such a way that it offers inter-format operability and hence can also be used on some of the other platforms of Autodesk software. The file is also supported by its open source ASCII version .DXF

Program(s) that can open the .DWG file


If you cannot open the DWG file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable application that supports DWG among those that are installed on your computer.

A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the DWG file can be found below. Now just download and install the appropriate application.

This site also defines other possible causes causing the problems with DWG files.

Possible problems with the files that are in the DWG format

The inability to open and operate the DWG file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the AutoCAD Drawing Format file. Below is a list of possible problems.

  • Corruption of a DWG file which is being opened
  • Incorrect links to the DWG file in registry entries.
  • Accidental deletion of the description of the DWG from the Windows registry
  • Incomplete installation of an application that supports the DWG format
  • The DWG file which is being opened is infected with an undesirable malware.
  • The computer does not have enough hardware resources to cope with the opening of the DWG file.
  • Drivers of equipment used by the computer to open a DWG file are out of date.

If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the DWG file should operate with your programs without any problem. If the problem with the DWG file has not been solved, it may be due to the fact that in this case there is also another rare problem with the DWG file. In this case, the only you can do is to ask for assistance of a professional staff.

How to link the file with an installed software?

If you want to associate a file with a new program (e.g. my-file.DWG) you have two ways to do it. The first and the easiest one is to right-click on the selected DWG file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK.

Is there a universal way to open unknown files?

Many files contain data in the form of text or numbers. It is possible that while opening unknown files (e.g. DWG) a popular Windows simple text editor, which is Notebook will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
