A cache is a file made by the operating system to make certain aspects quickly accessible and reduce fetch times and also the burden on your storage device. If you are having trouble displaying or using fonts such as fonts appearing garbled, fonts refusing to switch when you want them to or giving errors or crashing the program while switching fonts, then it may indicate that your font cache is corrupted.
To rebuild it, you need to clear font cache on Windows or Mac. You can safely delete these files since these are just caches and not the actual fonts stored on your computer. Once you clear the font cache on Windows or Mac, the next time your system starts, the operating system will check for the font cache, and once it is found to be missing, the cache will be reconstructed from the original files, thus fixing any issues that may be caused by corrupt font cache.
There are two ways to clear font cache on Windows. One is to stop caching service and manually remove all the files. However, you must have a reasonable level of comfort and confidence tinkering with your system. For example, if you delete the wrong system files, you may cause severe damage to your system. Another way is to use a simple font cache cleaner like Stellar BitRaser for the file.
Stellar BitRaser for file, besides acting as a font cache cleaner, can also help you in the cleanup of other junk files in your system. This program is specially made to erase unnecessary and unwanted junk. It can automatically find and clean traces of Internet activity and also traces of activities of other software. It has options that you can choose to delete any private emails, chat messages, or temporary files. It can also employ secure erasure techniques to erase private files such that they cannot be recovered or reconstructed. The secure erase technique can use one of 17 different standard or advanced erasing standards.
Tip: If you need to ensure that the data is permanently removed beyond the point where it can be recovered, you can repeat the process one more time. The data will be overwritten once more, and two passes would be enough to ensure that it cannot be recovered.
For Mac, you can either start your computer in the safe boot mode or use Terminal commands to rebuild font cache.
Malfunctioning fonts can be a major annoyance or even prevent you from doing your work altogether. It can be fixed by clearing the font cache using the simple steps mentioned in this article. However, the task can be made a lot easier by using a font cache cleaner like Stellar BitRaser for file, so that you can get back to work quickly.
