Temporary Files

Have you ever heard of “temporary files”, but had no idea what they are? Put simply, temporary files, also known as foo files, are files that are used by Windows operating systems, including Windows 10, to store information while a new file is being created. Usually, they’re used when a program doesn’t have enough available random access memory to perform its tasks, when the program is dealing with data that is larger than the computer’s architecture’s address space, or when two or more processes need to communicate with each other. When programs don’t have enough memory to perform their tasks they may employ the use of virtual memory, but some programs such as video editors may still need to use temporary files.
Normally, temporary files in Windows 10 have the “.TMP” file extension and are stored in two locations: “%systemdrive%\Windows\Temp\” and “%userprofile%\AppData\Local\Temp”. The latter path is used for user-specific temporary files.
Lots of programs fail to delete their temporary files when they are closed. The result is a pile up of unnecessary temporary files that can slow down the system and take up lots of storage on your computer. Lots of people think it is dangerous to delete the temporary files, but in reality they can be cleared without any danger to the system very easily, because if there are any temporary files needed by the system, they will rebuild themselves. If your computer is slow, or it’s running out of storage, this is an easy and effective way to remedy the situation.
