These files are dynamically linked libraries commonly associated with software installers that employ data compression techniques. Specifically, these DLLs often handle the decompression of archive files during software installation processes. When encountering issues during installation, such as error messages indicating that these DLLs are missing or corrupt, the installation process may be interrupted.
The correct functioning of these files is vital for successful software installations, particularly for games and applications utilizing highly compressed data. Historical context reveals that their prevalence grew alongside the increasing size of software packages and the corresponding need for efficient distribution methods. The availability and integrity of these libraries directly impact the user experience by ensuring a smooth installation process and minimizing potential errors.
