The Dynamic-link library or the DLL file format has been developed by the Microsoft Corporation. The file extension is an implementation of the shared library concept in the OS/2 and Windows operating systems. Such libraries normally have file formats OCX and DLL or DRV. The DLL files are very much similar to the Windows .EXE files that are PE (Portable Executable for both 32 and 64 Bit Windows. The DLL files consist of data, codes and resources in different combinations.
Data files with similar files as the DLL, but with different formats possibly comprise of the resource sections, and are commonly called as the resource DLLs files.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .DLL file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .DLL file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .DLL file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
