The developers of the operating systems are aware of the risks that exist not only in the network but in the bad manipulation of many of the system's own services and processes . For this reason they take certain security measures to avoid this, we talk about hidden folders and files ..

Many of these folders and files integrate configurations, some more delicate than others, of the system and its variables so, if we get to erase any of them by accident, or perhaps not so accidentally, we can generate a cascade of adverse situations that can impact negatively in the performance and performance of the system. That is why it is key that the Operating System itself assumes the responsibility of putting the most important files of our team in good standing and ceases to be a temptation to modify them. Even so, we may have hidden files and folders ourselves at some point and then forget it by going crazy when trying to find them.
