    DLL stands for Dynamic Linked Library.

    So lets assume you are running an application say eg: Photoshop.

    it is a big application.So it needs lotta memory space.for example there are like 1000 objects that a program(in this case its PS) uses,it does not uses all of em at a time.lets say its using 25 objects at this instance so the rest if loaded into memory is a waste.so what programmers do is they divide them into DLLs like for instance 50 each.

    so now again consider the above scenario so the app needs 20 objects then the particular dll is loaded to the memory thus saving memory.

    there are broader things to talk about dll.but this solves your question.lets keep it that way

    .DLL files are meant for the purpose of providing support to the programs running and hence you should not play around with these files as they are essentilal for the running og the different programs.
    it is supposed to save space and help in maintaing the architecture of the windows however it can also render the system unsafe.for more information go to following:

    DLL is defined as the Dynamic Link Library. It is the Collection of the Small Programs which can be called when needed by the Executable Programs.

    This allows the Program about the information of the Free Space, without writing all the Source Code in the same Space. It saves the Space on the Hard Drive. When DLL is used in this way, it is called Shared Files.

    Hello Friend,

    "A Dynamic Link Library (DLL) is a file of code containing functions that can be called from other executable code (either an application or another DLL). Programmers use DLLs to provide code that they can reuse and to parcel out distinct jobs. Unlike an executable (EXE) file, a DLL cannot be directly run. DLLs must be called from other code that is already executing."

    Another way of putting it is that DLL files are like modules that can be plugged into different programs whenever a program needs the particular features that come with the DLL. The original concept behind DLL files was to simplify things. It was recognized that there were many functions common to a lot of software.

    In other words the .dll files are used mainly in the graphical applications.
    You might have seen that there will be a lot of .dll files which are present in your game folders.

    Examples of Important DLL files
    COMDLG32.DLL
    Controls the dialog boxes
    GDI32.DLL
    Contains numerous functions for drawing graphics, displaying text, and managing fonts\
    KERNEL32.DLL
    Contains hundreds of functions for the management of memory and various processes
    USER32.DLL
    Contains numerous user interface functions. Involved in the creation of program windows and their interactions with each other


    Regards
    -Abhishek

    .DLL in windows 7 tends to dynamic link library. .Dll is a collection of small program.
    This small program work as a resource program of executable program (EXE) that is
    running on the system.

    When a EXE program needs the free space of your hard drive. It can call the DLL file
    that contains the function with parameters and a call function. The DLL will then tell
    the executable the free space. This allows the executable to be smaller in size and
    not have to write the function that has already exists

    For loading a DLL file, an executable needs to declare the DLL function. A DLL may have
    many different functions in it. Then when needed the call is made with the required parameters
