Memory on a device is made available by clearing the cache. Files downloaded straight from the web are kept in memory by a browser cache. Clearing it can solve user issues, such as the following:
- Applications with full cache memory risk crashing or loading incorrectly.
- Old caches can contain outdated information and files, causing webpages to not load or load incorrectly. Clearing them can get rid of outdated information.
- Personal data kept in browser caches, such as passwords, is also there. The user can be protected by clearing them.
- Most browser caches can be cleared by going to settings.
A cache should be cleared periodically, but not daily. Clearing the cache too often is not a good use of resources because of these issues:
- The user loses the benefit of quick file access;
- Caches delete some files on their own and don't need this sort of maintenance; and
- The computer will cache new files and fill the space up again.
