What is BLK file?

The file with the extension BLK is the CAD Files file type. The creator of this file is Autodesk. Additionally, the CAD Files category contains 158 of other files. AutoCAD Block Template Format is supported by 1 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows. It is recommended to use AutoCAD to handle this file. This is a program created by Autodesk, Inc..

How to open BLK file?

The main problem with AutoCAD Block Template Format is that the BLK file is incorrectly associated with programs. Thus, when you open BLK, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the BLK file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install AutoCAD

In this case, you should first verify that the AutoCAD application is installed on the computer. This can be achieved by typing AutoCAD into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file BLK with AutoCAD. Below is a list of programs that support the file BLK.

Programs to open BLK file

Remember to download programs supporting BLK files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of AutoCAD with BLK files

If, despite the installed application, the BLK file does not start in the AutoCAD application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the BLK file with the AutoCAD program.

Step 3. Update AutoCAD to the latest version

The fault may also lie with the AutoCAD program, it is possible that AutoCAD Block Template Format requires a newer version of the program. In this case, use the Autodesk, Inc. website or update the program from the application.

Step 4. Check for the following problems with the BLK file

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

Very often, the file may be size 0 or incomplete. Usually this applies to BLK files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the BLK file that we want to open. Sometimes virus-infected BLK files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the BLK files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged BLK files. The easiest way to restore the file is from a backup or by contacting Autodesk, but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted BLK files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. If possible, you can try to move the BLK file to another location.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the BLK file while scanning. If this does not work either, restart the device.
