What is CLW file?

The CLW file has been categorized as Developer Files. It was designed by Microsoft. Additionally, the Developer Files category contains 1205 of other files. Visual C++ ClassWizard Format is most often found on 1 operating systems. These systems consist of Windows, although it may occasionally be found on another system, it will be non-functional. The Microsoft Visual Studio application is recommended to open the file. It was released by Microsoft Corporation. Alternatively, you can use 1 other programs. Visual C++ will apply when it is not possible to use Microsoft Visual Studio.

How to open CLW file?

The main problem with Visual C++ ClassWizard Format is that the CLW file is incorrectly associated with programs. This is manifested by the fact that CLW files open in unusual applications or do not have an assigned program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the CLW 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 Microsoft Visual Studio

In this case, you should first verify that the Microsoft Visual Studio application is installed on the computer. The easiest method is to use the system search engine by entering the program name Microsoft Visual Studio in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open CLW files.

Programs to open CLW file

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

Step 2. Create association of Microsoft Visual Studio with CLW files

If the application is or has been freshly installed, but the CLW file still does not use the Microsoft Visual Studio program, it means no 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. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. The "always use the selected program ..." field will set the Microsoft Visual Studio application as the default for handling the CLW file.

Step 3. Update Microsoft Visual Studio to the latest version

If, despite the association of the Microsoft Visual Studio program with the Visual C++ ClassWizard Format file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the Microsoft Corporation website and install the latest version.

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

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

The CLW file may be unusually small compared to the original file. This is most often caused by a problem while downloading the CLW file. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. 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 CLW file that we want to open. Sometimes virus-infected CLW 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 CLW files changes over time. These problems are known and are often very easy to fix using the software developers's website.
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 option of recovering data from damaged CLW files. The easiest way is to restore the file from a backup, if there is one, or contact Microsoft
The program can also signal the fact of encryption. The encrypted CLW 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. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the CLW file to another location.
This problem usually affects more complex files. In this case, the CLW file is blocked by the first application to open it. Just close unnecessary programs. Sometimes you have to wait for the session to the file CLW to close. However, some background programs may block the CLW file while scanning. If the problem persists, restart the machine.
