File extension .3DF

File description

3DF file format is used as 3D format. This file format is used to store 3D object information.

This file format is used to view the 3D object. The main purpose of converting other file formats to 3DF format is to secure the data and to reduce the size of the file to make it easy for sharing purposes. This file format allows the user to achieve 78 to 90 percent compression ratio over the original file. This file format is only used to view the object stored in the file and therefore this file stores the rendering information about the file excluding the mesh frame.

The .3DF file extension can correspond to several not related file formats. If there is more than one file format with the .3DF extension, you will probably find most of them at this website. Remember that you need to download a program to support a particular file type. So first look through the entire contents of the website to select a program to support just the file you have.

Other possible reasons why your .3DF file does not want to open

In addition to the problem described above, i.e. the lack of the appropriate application to support the .3DF file, there may be several reasons that cause problems with opening and operation of the data format:

1. Incorrect version of the installed application

A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .3DF file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .3DF file, so download the update and check again.

2. Incorrect .3DF file association with the program

If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:

  • Right-click the .3DF file
  • Go to the "Open with" - then "Choose default program ..."
  • Locate the appropriate application
  • Click "OK"

3. The file is corrupt

It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
