Know about .DLL File?

What is DLL File?

A DLL short for Dynamic Link Library, A Dynamic Link Library is a small piece of software code that is responsible for doing a simple task for a wide range of different applications inside the Windows operating system of your PC. These libraries generally have the DLL, OCX or DRV File extension. DLL file is a file that contains instruction through which other program can call to perform certain operation. It is Useful because they allow a program to separate its individual component into unique module. Then it can be added or removed to include or exclude certain feature. If the software works with DLL files then the program can use less memory because it does not have to load everything at the same time.

How DLL file get corrupts

There are various reasons that are responsible for the DLL file corruption. Here we will discuss about the cause behind DLL file corruption:

  • Sometimes installing a program can replace existing DLL files with older files. This often happens when installing completely new software on a Windows computer. When this happens, programs that share this specific DLL file will start to experience errors, because of the “new” file that does not have the data needed to run.
  • Defective and defective hardware, usually hard disks, can corrupt files that are in use. This happens when the bad hard drives work and corrupt the files in use. Sometimes a bad memory of the computer can also corrupt DLL files. On other occasions, the registry and its DLL files may become corrupt due to wrong behaving applications or software.
  • The most common reason for corrupted DLL files is system infestations by the foregoing. These programs can “worm” in the Windows registry and corrupt or completely replace existing DLL files. When this occurs, Windows becomes much more prone to DLL errors and may even stop working properly.
