File description

BLK file extension, developed by Autodesk AutoCAD, is basically a template for users of Mac OS X and Windows operating systems. Parts of files stored in BLK format are in the form of CAD drawing which are helpful in publishing drawings as PDF or DWG.

The files also help in managing information which is published to any of the sharable files and therefore, they facilitate in controlling the distribution of data. BLK file extension is a utility that enables users to store certain image components which are intended to be published in DWFX, PDF or DWF formats.  All in all, BLK is a beneficial 3D and 2D application that can be easily created by Attribute Extraction wizard or Block Template dialog box.

Programs that will open this file:
The .BLK file extension can correspond to several not related file formats. If there is more than one file format with the .BLK 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 .BLK file does not want to open

In addition to the problem described above, i.e. the lack of the appropriate application to support the .BLK 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 .BLK file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .BLK file, so download the update and check again.

2. Incorrect .BLK 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 .BLK 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.
