DLL files are an important part of the Windows operating system. DLL stands for Dynamic Link Library and is a file which contains code that is responsible for running important programs and applications in the Windows OS. DLL files should never be deleted from the operating system, especially if you are not sure what programs they are associated with.
Unlike an EXE file which is responsible for running programs and applications, DLL files are summoned from other codes which are already running in order to access specific features in different programs and applications. The purpose is to reduce complexities associated with running programs. For example, instead of using a separate code to run the interface for a program, DLL will be called upon by an EXE program to run the interface for that specific program.
If you have ever looked at the files contained in your PC under Windows Explorer or in the registry, DLL files are the ones that end with the extension .dll. You may have also come across a problem with opening programs and have experienced the error message that refers to missing DLL files. Since DLL files are an essential part of EXE programs, a missing or corrupt DLL file can cause a program not to function.
How to Open DLL Files
DLL files are typically used by programmers to discover the purpose and functions that each file serves in terms of aiding other programs. The typical PC user really has no need to open a DLL file, and if you do not know what you are doing, you could accidentally edit the file which will in turn render one or more of your programs useless.
If you know what you are doing when it comes to working with DLL files, there is more than one way to open a DLL file. For this reason, you should first decide whether you want to simply view the contents of the file or you want to review it to discover the programs in which the file is associated. DLL files can be called up by more than one program running on your PC.
You can open a DLL file using your word processing program or WordPad. Once the word program is open, click on File on the main toolbar and then click on Open. Navigate to My Computer and then open Windows Explorer to find the DLL file you want to examine. Open the DLL file you want to review, but be careful not to accidentally modify any of the data related to the file. Inadvertently editing the data could affect the functioning of multiple programs on your PC.
As a word of caution, when uninstalling programs you must be careful when removing a program from your PC. As a general rule, you will be prompted when a DLL file is associated with other programs on your PC. You will be asked if you want to go ahead and remove the DLL file. In this case, click No on the prompt to preserve the functioning of other programs on your PC. Additionally, if a DLL file is missing or becomes corrupt for any reason make sure you are obtaining a new DLL file from a trustworthy source. Or, if you are not sure what to do make sure you enlist the help of a PC technician that understands DLL files and the functions they serve.
