What is COF file?

The file in the COF format belongs to the Data Files category. The author of this format is Autodesk. In addition to this file, the Data Files category includes 1326 related files. AutoDesk Data Format appears on 1 operating systems as a functional file. The file will work on Windows systems, unfortunately not on others. The AutoCAD application is recommended to open the file. It was released by Autodesk, Inc.. There are also 1 alternative programs to handle the COF file. AutoCAD Civil will apply when it is not possible to use AutoCAD.

How to open COF file?

The main problem with AutoDesk Data Format is that the COF file is incorrectly associated with programs. This is manifested by the fact that COF files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the COF 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. The easiest method is to use the system search engine by entering the program name AutoCAD in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support COF files.

Programs to open COF file

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

Step 2. Create association of AutoCAD with COF files

However, it may happen that the application itself does not cause the COF file to open in the AutoCAD application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. 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 COF file with the AutoCAD program.

Step 3. Update AutoCAD to the latest version

If, however, after binding AutoCAD with AutoDesk Data Format there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Autodesk, Inc. page and install.

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

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

Very often, the file may be size 0 or incomplete. Usually this applies to COF files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the COF file that we want to open. As a result of the scan, sometimes it is not possible to recover COF files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of COF file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair COF file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Autodesk
The program can also signal the fact of encryption. The encrypted COF 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 of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. Copying the COF file to another location will fix the problem.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the COF file again. Some anti-virus or backup software may occupy the COF file for a certain period of time. If this does not work either, restart the device.
