What is CU file?

The file with the extension CU is the Developer Files file type. The creator of this file is NVIDIA. In addition to this file, the Developer Files category includes 1205 related files. CUDA Source Code Format appears on 1 operating systems as a functional file. The file will work on Windows systems, unfortunately not on others. There are also 2 alternative programs to handle the CU file. Text editor, Windows Notepad will apply when it is not possible to use NVIDIA CUDA Toolkit.

How to open CU file?

An often recurring problem with CUDA Source Code Format is that CU is not associated with the correct program file. Thus, when you open CU, the program selection wizard or some other program starts. How to solve such a problem?

The first thing you should do is just "doubleclick" on the CU 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 NVIDIA CUDA Toolkit

An often overlooked issue is to make sure that NVIDIA CUDA Toolkit is installed on the computer. To do this, enter the name NVIDIA CUDA Toolkit into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open CU files.

Programs to open CU file

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

Step 2. Create association of NVIDIA CUDA Toolkit with CU files

If, despite the installed application, the CU file does not start in the NVIDIA CUDA Toolkit application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Changes can be made using the "Change" button. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the CU file with the NVIDIA CUDA Toolkit program.

Step 3. Update NVIDIA CUDA Toolkit to the latest version

The fault may also lie with the NVIDIA CUDA Toolkit program, it is possible that CUDA Source Code Format requires a newer version of the program.

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

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the CU file. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file CU or the program directory. However, remember that not every infected CU file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the CU files changes over time. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair CU file corruption.
When reading, a message appears that the file was encrypted or corrupted. The encrypted CU 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.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. It is best to move CU to a different directory.
This can happen on a file that does not support multiple access. 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 CU file again. Some anti-virus or backup software may occupy the CU file for a certain period of time. If the problem persists, restart the machine.
