Internet Paso a Paso

If it ever happened to us that when we check our mobile device and also our computer we find files that we cannot delete in the traditional way as we do with others, we are in the presence of files that are called "Protected by the operating system".

The cause of this may be because it belongs to applications that are being used and the deletion could cause them to malfunction. Another origin may be that applications that we no longer have installed left these files.


The third reason why these protected files may exist is for those who use the operating system for normal operation. We will talk in this article about what files we can delete and why they exist on our devices, we will also present you the best tools so you can eliminate it without problems.

Why is there data that cannot be deleted from my computer?

If we have little space on our hard drive to store data, one of the first steps we do is to delete the temporary files, cookies and all other junk files that we have in the browser or in the same operating system.

When we realize that we still need more space, we begin to analyze what data we can erase. At this time is when we have doubts about what data we can not remove from our team.

The operating system is composed of different hierarchies of folders, which save the commands for a correct and efficient work of the software. Some of this data is intended to facilitate and manage resources so that hardware can be accessed as well as other parts of the software.

In this way, the operating system considers these data as vital within it, so they are protected and are generally hidden.

It follows that we can't erase that kind of data to get more disk storage, since we would significantly harm the operating system and the proper functioning of the hardware.

Is it dangerous to delete these files protected by the system?

It is dangerous to delete these files protected by the system

There are, as we named above, other files that are protected by the system and are those that are being used by other applications that, if we delete them, the most we can cause is that those same programs do not work properly.

It follows that we have to perform a previous analysis to determine if the applications that we have installed on our device are all necessary, so if we find some that are not, we can eliminate them and at the same time we can erase all the data that the system operational protected for them to work.

We conclude, then, that after a previous study deleting this kind of data protected by the system is not dangerousWe simply have to be careful to eliminate them only and not touch someone else.
