• Please note that these files are not executable, meaning they represent code that must be opened somewhere on the system.
• They do not duplicate unnecessary resources, but perform their functions with different programs, thus saving space on the system.
• Sometimes a DLL file cannot be opened and produces an error that must be resolved in order to run the application or programs you want.

• They can be easily updated and recovered as there are many websites that offer downloads free and safe DLL file extensions.
• DLL files are multilingual, which means they can read the language used on the computer.

Disadvantages

• In some cases, DLL files may present compatibility and readability issues after a system or software update.
