The DLL error is one such error that appears on computers running the Windows operating system. The name itself may sound scary to any computer user but these errors can be easily resolved once the user understands their nature and causes.
The term DLL is the short form for Dynamic Link Library. This library was created by Microsoft in order to reduce memory and hard disk space that the programs and operating system take up while running, thereby improving the overall efficiency of the computer. This was crucial in the days when the memory and hard disk space were limited. So, whenever a common process was required by multiple programs, its programming code was placed in a separate file that was referred to as DLL or Dynamic Link Library. So, instead of uploading the process separately for different programs, the operating system uploads the DLL file only once.
DLL files have been acclaimed as a good idea but like all things related to technology, it may develop problems or sometimes malfunction. Some of the reasons why a DLL error occurs are:
- A user may unknowingly uninstall a DLL file.
- A user may be trying to install a DLL file which is already corrupt
- Problems in the hard drive may cause damage to a DLL file.
- Malware infection may corrupt a DLL file.
