File Extension SYS

In this article I'd like to cover file extensions used in files which store different type of electronic documents. More specifically we will discuss EXE, SYS, COM, LNK and DLL file extensions.

There is a chance you wondered what happens when you select certain application in Windows and start it. When you start some application from the start menu what actually happens is that Windows start

EXE file associated with this application. File extension EXE stands for executable. This file contains commands coded in machine language which computer executes and as result you see functional application.

In pre-windows world COM file extension was very popular. It stands for command file and was used by MS-DOS for application files.

File extenson SYS stands for system file. It is very frequently used by operating system to store parts of executable code. An example of SYS files is config.sys which is used to store system configuration. Another example is pagefile.sys which stores windows paging file (disk dump of system memory).

LNK is a file extension which stands for LINK. This file links an item in windows start menu with executable file (EXE or COM file). DLL contains helper system code which is used by applications for certain features. File extension DLL stands for Dynamic Link Library.

Every executable file contains low level assembly commands which only computer CPU understands. You can decode these files using disassembler. But it is not recommended for average computer user to perform this operation. Usually executable files are very hard to view and only could be edited and viewed by professional software engineers.

If you cannot open executable file something may be broken in windows operating system. To check for problems you may have to read through windows documentation. One more possibility is windows registry error. To check for registry errors you could download registry cleaner.
