The dev file extension is used for Windows Device Drivers. A device driver, or software driver is a computer program allowing higher-level computer programs to interact with a device.
Typically, dev files are stored in the Windows System folder and should not be opened or altered.
A driver typically communicates with the device through the computer bus or communications subsystem to which the hardware is connected. When a calling program invokes a routine in the driver, the driver issues commands to the device. Once the device sends data back to the driver, the driver may invoke routines in the original calling program. Drivers are hardware-dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface.
Drivers are used by the OS to handle various hardware, they are not for users to open or edit.
These files are generally not mean to be converted to anything else.

TeX is a computer language and typesetting system designed especially for mathematics and other technical material. The name comes from the Greek word for art or craft, and is conventionally pronounced with a Greek chi sound, roughly like "blecch", rather than like the name "Tex" associated with Tex-Mex chili.
A Device Independent TeX file contains data produced or used during TeX processing. It is an intermediate file in the TeX workflow, so its contents are intended for TeX-related tools rather than for direct editing by the user.
TeX is freely available on Windows, macOS, Linux and other platforms through TeX distributions.
Open a .dev file with the TeX distribution or TeX-related tool that created it. TeX software is available for Windows, macOS and Linux, but a general-purpose text editor may not be able to interpret the file correctly.
If the file is an intermediate output file, it may need to be processed together with the related TeX document and supporting files rather than opened by itself.
A .dev file generally has no useful standalone conversion method. If the original TeX source is available, the preferred approach is to process that source again and generate the required output format, such as PDF.
Conversion of an existing file depends on the particular TeX tool that produced it. Keep the original source and supporting files when possible, because they provide the most reliable route to another output format.
