If you want to "unpack" important aspects of your computer, you may want to find, open, or edit a dynamic link library (DLL) file. A DLL file is a small component of a program. As library files, DLLs contain modules for specific functions. The existence of a DLL file will greatly simplify the architecture of a program. If you need to edit a DLL file, open the file with a decompiler program, make the necessary changes, and then recompile the file with the same program.
Step
Step 1. Locate the DLL file
DLL files can generally be found in the same folder as the main program. However, some DLL files are stored in different folders. You may need to locate the DLL file you want to edit in some local folders.
Step 2. Find out what DLL files are used for
DLL files contain code elements that are used by other programs. To edit a DLL file, you must know which program is using the file. Some DLL files are used by more than one program, making editing difficult. In order for the editing process to be successful, make sure that the DLL file you are about to edit does not affect any programs on your computer.
Step 3. Download a decompiler program to edit the DLL file
Like whole programs, DLL files are translated from high-level code to machine language (binary and the like). Therefore, to read the contents of a DLL file, you must convert the DLL file back into a human readable file. This process is known as decompile.
Step 4. Open the DLL file with a decompiler program
Step 5. Make changes to the file as needed
You can modify a DLL file in a number of ways, depending on what you're editing the file for.
- Use an icon extracting program to extract the icon from the DLL file. One of the most common reasons for editing a DLL file is to change the icon or visual symbol on the desktop or a specific program. To do this, computer experts advise you to use special programs. An icon extracting program will make it easier for you to edit icons in DLL files.
- Make further interface changes by changing the human-language code you find after the file decompile process is complete.
