Open DLL File

Open DLL File

Lib file extension is used for files which typically store static libraries. Static library is a compiled binary file which contains function definitions which an application can use when the library is linked to it. LIB files are typically not delivered as part of end-user applications: instead they are merged with the executable file of an application. Static library files could be created by development software such as Microsoft Visual Studio, XCode, gcc.

Sometimes LIB files are used as data or library files. For example, a game can store its graphics, 3d maps, 3d objects, etc. in LIB files and read them when content becomes necessary. LIB files in this case can be quite large because they can store significant part of a game or an application content. Typically, files in LIB library format are binary and it is impossible to read or extract data from them without specific tools which are specifically compatible with such LIB files. LIB data files don’t have a specifically defined structure for them and can be stored at any format game developer decided feasible.

Finale by MakeMusic and LIB files

An example of an application which uses LIB file extension as a library file is Finale by MakeMusic. Finale is a music notation software and it uses LIB files to store sets of symbols (such as Chords or Articulations), markings (such as Text Expressions) or settings (such as Document Settings or Spacing Width). Finale LIB files are only compatible with Finale software and only Finale software can open them. For more information refer to Finale file extensions and icons webpage.

LIB Directory

Lib directory is the directory which stores operating system kernel modules and library files shared between different applications. Library files located in LIB directory usually don’t have any file extension assigned to them or have .SO file extensions. Library files in LIB directory are also executable but it is not typical for them to run as a standalone application. They are launched and called when main application requests them.
