What is a CVF file

CVF files mostly belong to CPU-Z by CPUID. A CVF file contains system information collected by CPU-Z system performance analysis software. CPU-Z collects information about a computer's CPU, GPU, motherboard, storage, and memory. The Validator application on GPUID website uses information saved in a CVF file to validate the authenticity of a computer's configuration/specification by comparing it to information in CPU-Z's database. Another type of CVF file contains game data used by Metal Assault - Gigaslave action shooter video game.

How do you open CVF files?

You need a suitable software like CPU-Z to open a CVF file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your CVF file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a CVF file directly in the browser:. Just drag the file onto this browser window and drop it.

CVF format details:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. When there is a problem with a file, the first step to solving it is to determine the file format. Our examination of the CVF files comes to the following conclusion:

The CVF file ending predominantly uses a uniform format. But the following two file formats are common:

70% of all CVF files start with the bytes CPUZCVF200# crucial for this file format. The contents of these files cannot be read by a human; only a computer program can interpret the data. CVF files are between 17 KB and 26 KB in size. The file type was created recently. The keywords CPUZCVF200# are typical for these files. Examples of file names are cpuz.cvf.
10% of all CVF files start with the magic bytes úæ,î÷åø,îùôçä,ôøèé,ñîì éùåá,éùåá,÷åã øçåá,øçåá,îñôø,àåú,ëðéñä,ãé, which are always the first bytes of this file format. They consist of unreadable binary data. Most of these files are 3.3 GB to 3.3 GB in size. The following filename is common: 3.CVF.

All other CVF files (20%) have no consistent format, often, for example, Jet-VoiceMail audio data and SFILESYSTEM. If you want to find out which format your CVF file belongs to, just click on the button "Choose your .cvf file to analyze".

How to solve problems with CVF files

Associate the CVF file extension with the correct application.
Update your software that should actually open validations. Because only the current version supports the latest CVF file format. Search, therefore, e.g. on the CPUID manufacturer website after an available CPU-Z update.
To make sure that your CVF file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
