What are temp files?

Temporary files are temporary data files created by Windows or the program itself that help the computer to run related tasks successfully. They are also called foo files and have .temp as the extension.

In essence, there is no difference between temporary files and virtual memory, except that temporary files are more targeted than virtual memory and serve a program alone. The path of temp files varies by program and operating system. But for Windows, the directory for temp files is generally stored in the AppData folder(C drive). So, some users may need to move AppData to another drive for saving more space.

For example, when a user is browsing a website, in order to improve the access speed of our next login to the website, cookies will generate a temporary file to record the user's identification and other information. If uncleaned for a long time, these temporary files can take up a lot of disk space and slow down Windows performance. Deleting temporary files can free up disk space to keep Windows running properly.
