Tmp files (temp files), also known as Temporary Files, are files that programs save on your computer to keep information for a short amount of time in case the system needs the same data again. Other sorts of temporary files in Windows include those left over after installing a new version, upgrade logs, error reporting, temporary Windows installation files, and more.
Is it OK to delete all temp files?

They are only useful when they are generated for specific programs. So, when you cease the running program, some of them will be outdated and useless. The new temp files will emerge when users run the program. Thus, it’s safe to delete all temp files.
