You may have already encountered the “$ WINDOWS. ~ BT “and” $ Windows. ~ WS ”on your Windows PC. This happens when you have enabled the option to show hidden system files. Two folders present in Windows, of great importance and we will now explain to you how to eliminate them without taking any risks.

These are two files whose names are very difficult to pronounce and even more difficult to write. These two folders are created automatically by Windows 10 when you go to install a new update, but they can be removed by following these steps.

What are these folders and how to delete them

But the first thing is to explain what the $ WINDOWS folders are for. ~ BT and $ Windows. ~ WS. These are, as we said before, two folders that Windows 10 automatically creates before launching a major update like the one that usually arrives in the spring and fall.

These folders are only visible if you have the option “Show hidden files” active in the system and the objective of both is to try to avoid that during an update an issue can arise as backup files. And each has a specific function:

$ WINDOWS. ~ BT is the folder that stores the data of the current version of Windows 10 before the update, so that in the event of an unforeseen event, Windows can revert to the previous version and avoid the problems that the new update may to have.

$ Windows. ~ WS This folder stores the installation files for the next version and extracts the files from Windows to install the update.

Once the computer has been updated, these folders are no longer necessary and their deletion can generate significant disk space, especially on fairer computers. But that doesn’t mean that they can be eliminated like crazy and that you have to follow a series of steps to avoid problems.

To delete these folders, you must first have Windows enabled the “Show hidden files” option, available in the “Vista” tab of “File Explorer”. But no, it’s not about sending them to the trash.

We are going to use a Windows option. We go to the “File Explorer” in the hard disk space and click on any free place with the right button while selecting “Properties” in the pop-up window.

The window C: “Properties” will open and we are looking for the “General” tab where we should find the “Free space” button.

By clicking on “Free up space” a new window will open to free up space on the hard drive and the option we are interested in is the one called “Clean up system files”, a special function that allows you to delete internal operating system folders and this is the case with “$ WINDOWS. ~ BT” and “$ Windows. ~ WS”.

Clicking on “Clean up system files” will bring up a screen to delete the files from the system and in it we have to check the boxes “Clean up Windows updates” and “Previous installations of Windows”. All that remains is to click on accept and the “$ WINDOWS. ~ BT “and” $ Windows. ~ WS ”will be historical, at least until the next update.
