How to open a sys driver file. How to open a sys file? How to associate a file with an installed program

The SYS file is a system file containing the code required for the correct launch and settings of the Windows operating system. This type of file was also used by MS-DOS. Quite often, SYS files are downloaded along with the Windows operating system; in more rare cases, the SYS format is installed with certain software packages.

System files can relate to drivers, being responsible for storing all kinds of instructions for the full functionality of these drivers. Experts recommend that inexperienced users do not try to open a file with the SYS extension, much less change it, because the .sys file can carry important system information; if the file data is damaged, adverse consequences associated with the Windows system are possible.

It is worth noting that it is not recommended to download a file with the .sys extension from third-party unreliable resources. In some cases, a changed description of a file with the .sys extension can even lead to the collapse of the entire Microsoft Windows system. This file extension facilitates the timely completion of planned operations.

Files with the .sys extension may contain links to certain DLLs. Files with the SYS extension are opened using built-in applications of the system; when you hover and click on the file, Windows will be able to open the SYS file. This file format, in some cases, can be edited in a text editor. If file associations are configured correctly, the corresponding system application will be able to open SYS. It is noteworthy that before opening the .sys file manually, the system may ask the user which program to use as the default in the future for such an extension.

This may seem too obvious, but often The SYS file itself may be causing the problem. If you received a file via an email attachment or downloaded it from a website and the download process was interrupted (such as a power outage or other reason), the file may become damaged.

Thus, it is likely that your computer does not have enough memory(commonly called "RAM" or random access memory) to perform the task of opening a file.

Try refreshing your memory to see if this will help you open the SYS file. Today, memory upgrades are quite affordable and very easy to install, even for the average computer user. As a bonus, you you'll probably see a nice performance boost while your computer performs other tasks.

Developed by Microsoft, the SYS file format was designed to store compiled system resources like configuration variables and settings required by Windows and DOS (Disk Operating System) for performing its intended operations. Also known as Windows system files, the content of a SYS file normally consists of core Windows and DOS components like driver resources and references to corresponding Dynamic Link Library (DLL) modules. The io.sys file, for example, contains DOS initialization code and driver resources required by DOS, while the config.sys file stores system variables and configuration settings of Windows and DOS. The content of these SYS files can be viewed or edited by using applications that have been built into Microsoft Windows.
