The primary purpose of a software patch is to fix vulnerabilities and improve functionality. Patches are typically released by software developers to address specific issues that have been identified after the software's initial release. This can include fixing security vulnerabilities that could be exploited by attackers, which is crucial for maintaining the integrity and security of a system. Moreover, patches can also enhance existing features or functionality, ensuring that the software operates smoothly and efficiently.

Adding new features is usually the domain of software updates or upgrades, rather than patches, which are intended primarily for fixing problems. While some patches might coincide with minor feature enhancements, the core focus remains on addressing and resolving issues. Deleting obsolete files is generally handled through maintenance processes rather than patches, and upgrading hardware is related to physical improvements rather than software modifications, therefore it is not relevant in the context of patches.
