The DEV file is supported on 2 operating systems. Depending on your operating system, you may need different software to handle the DEV files. Below is a summary of the number of programs that support and open the DEV file on each system platform.
What is DEV file?
The file in the DEV format belongs to the System Files category. System Files consists of 323 similar files. Windows Device Driver Format is supported by 2 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Mac OS, Windows. This file type can also be opened by 1 other programs. You can use Microsoft Windows in case Parallels Desktop cannot be used.
How to open DEV file?
The main problem with Windows Device Driver Format is that the DEV file is incorrectly associated with programs. Thus, when you open DEV, 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 DEV 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 Parallels Desktop
In this case, you should first verify that the Parallels Desktop application is installed on the computer. This can be achieved by typing Parallels Desktop into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support DEV files.
Programs to open DEV file
Remember to download programs supporting DEV files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Parallels Desktop with DEV files
If, despite the installed application, the DEV file does not start in the Parallels Desktop 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. Using the "Change" button we can set the program to handle this type. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the DEV file with the Parallels Desktop application.
Step 3. Update Parallels Desktop to the latest version
If, despite the association of the Parallels Desktop program with the Windows Device Driver Format file, the file still does not open, check the program version and possibly update it to the newest version.
Step 4. Check for the following problems with the DEV file
If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:
Very often, the file may be size 0 or incomplete. Usually this applies to DEV files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the DEV file that we want to open. Sometimes virus-infected DEV 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 DEV 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 DEV files.
When reading, a message appears that the file was encrypted or corrupted. The encrypted DEV 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. Copying the DEV file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the DEV file again. However, some background programs may block the DEV file while scanning. If nothing helps, please reset the device.
