Deleting cache files is an important maintenance step that can help resolve various application issues. Cache files are temporary files created by applications to speed up their processes by storing frequently accessed data. However, over time, these cache files can become corrupted or bloated, leading to unexpected behavior or performance problems in an application.

When you delete cache files, you are effectively clearing out these temporary resources, prompting the application to create new, fresh cache files. This can help restore functionality by eliminating potential conflicts or errors caused by outdated or damaged cached data. It's a common troubleshooting step recommended when users experience issues such as freezes, crashes, or slow performance within applications.

In contrast, the other options do not specifically focus on handling temporary files. For instance, replacing application resources may involve modifying or updating app components, while checking diagnostic reports helps in analyzing system issues, but it does not directly rectify application performance. Installing system updates is crucial for overall system security and performance but does not specifically target the problem of temporary files.
