Let's look at how to delete temporary files from your computer.

Windows temporary files

What it is?

Temporary files in Windows are created in the system by various applications and the operating system itself in order to store data that is required for the current task.

Why are temporary files created?

Temporary files are most often created to transfer large amounts of information that are not profitable to store in RAM, or their volume is larger than the amount of RAM. Therefore, program developers temporarily store this data in a folder with temporary files, so that after some time their program or a separate module can use this information.

Temporary files are also created as a backup copy of the data you are currently working with. For example, programs in the Microsoft Office suite create temporary files with backup copies of the documents you work with. This is in case the office program crashes or the PC suddenly reboots. The next time you start it, you can continue working from the same place without losing the data in the document.

As a rule, temporary files should be deleted automatically after the application exits gracefully. But in fact this does not always happen. As a result, we observe a cluster large quantities temporary files that lie like dead weight and take up useful disk space on the system disk.

Where are Windows temporary files located?

In the operating system itself there are two places where it is customary to store temporary files. You can go to them from Explorer at the following addresses:

There are also cases when individual programs create a Temp folder in the root of the system drive C.

How to change where temporary files are stored

The operating system provides a way to change the variable folder in the user profile. To do this, in the environment variables ( Control PanelProperties of the systemAdditionallyEnvironment Variables) you need to change the storage folders for temporary files.

If you have several user profiles on your computer, you should not move the folder with temporary files for all users into one folder. First of all, this is not recommended for security reasons and maintaining stability, since it is unknown how this or that application will behave if it sees temporary files from another user in the folder. It's best to leave them where they are.
