Every computer user must have faced this hurdle of not being able to open certain file at least once in his working tenure. The problems can be many; one of them is absence of DLL files. So, don’t you want to know why DLL files are so important and what they do? Read on to unravel this mystery.

Dynamic-link library is Microsoft’s implementation of the shared library concept in the Microsoft Windows and OS/2 operating systems. These libraries usually have the file extension DLL, OCX (for libraries containing ActiveX controls), or DRV (for legacy system drivers). The file formats for DLLs are the same as for Windows EXE files – that is, Portable Executable for 32-bit and 64-bit Windows, and New Executable for 16-bit Windows. As with EXEs, DLLs can contain code, data, and resources, in any combination.

Data files with the same file format as a DLL, but with different file extensions and possibly containing only resource sections can be called resource DLLs. Examples of such DLLs include icon libraries, sometimes having the extension ICL, and font files, having the extensions. 

What DLL files are

DLL stands for Dynamic Link Library and are used for accessing shared code and data. It is an easy means to use upgraded applications without bothering to recompile them from the scratch. DLL files cannot be executed directly and therefore, the special execution files like rundll.exe and rundll32.exe are required for running these.

Another benefit of modularity is the use of generic interfaces for plug-ins. A single interface may be developed which allows old as well as new modules to be integrated seamlessly at run-time into pre-existing applications, without any modification to the application itself. This concept of dynamic extensibility is taken to the extreme with the Component Object Model, the underpinnings of ActiveX. 

How DLL files function

Any execution file that is required by a specific application requires certain imported functions that are stored in DLL files. When the execution file runs, DLL file folder gets the prompt of retrieving those functions which are required for running it. An export list, another list in DLL files has a number of addresses corresponding to the functions available in these files. Execution files simply employ these addresses to enable flawless running. 

Benefit of DLL files

DLL files are quite important in resource maximization as they can help running a number of applications. Since there is no need to download a separate set of information containing same attributes for each application, it enhances the speed and functioning of computer system. You may not require downloading numerous execution files to get access to varied applications and thus, the computer is able to run more numbers of these without too much of waiting time.

Errors commonly associated with DLL files

DLL errors may arise if the file asked for is not installed on the system, or whatever installed is actually an obsolete version. When the function required for running a program is not available in DLL file, it obviously cannot be found and thus, related application cannot be run.

A corrupt installation may lead to incomplete software with missing parts and this also may lead to nagging errors.

System requirements

DLL files run on all the latest versions of Windows and are compatible with both x32 and x64 bit platforms. 

How to get DLL files errors solved 

Fixing DLL errors is important as these may cause unwanted crashes and operational delays, if left unresolved.
