What are temporary files on PC?

Temporary files are produced in the Windows operating system by both the OS and the apps running on your computer.

Many of Windows' temporary files have the file extension ".tmp" or are preceded by a tilde. The majority of temporary files produced end up in the Windows Temp folder.

The location of transient files changes depending on the software and operating system. However, in Windows, the files directory is often saved on the C drive so that the system can immediately retrieve these files to ensure that your OS and running programs are working properly.
