Some people wonder if it is safe and possible to delete this folder or not. Let’s try to find out the answer to this question.

What is the $Windows.~BT Folder?

The $Windows.~BT folder is a temporary folder created by Windows OS to store essential files and components related to a feature update or a minor update. The name might seem cryptic, but it is actually a folder related to Windows OS updates.

This folder is created automatically when a new update is available. Windows automatically downloads all the necessary update files and stores them in this folder. Once a user installs the feature update, Windows removes this folder from the directory after a period of 10 days.

The folder’s size depends on the size of the update and whether it has been installed. A small-sized folder indicates remnants of a recently installed update or a minor update. A larger folder means that the user is yet to install the update.

This folder’s primary function is to store previous OS version files. But, in the process, it eats up a significant amount of storage space. In some cases, these files are used in case an update turns out to be buggy, or the user wants to revert to the old OS. The folder acts as a contingency plan in case a new OS update doesn’t turn out as stable as the previous one.

The $Windows.~BT is usually located as a hidden folder in the C: drive. However, in some rare scenarios, it gets created in the Downloads folder.
