What is a TMP file?
A TMP file is a temporary file created automatically by a software program that usually serves as a backup or cache file. It is sometimes created as an invisible file and is often deleted when the program is closed. TMP files may also be called "temp files."
Often a temp file is comprised of raw data which is used as an intermediary step in the process of converting the content from one format to another.
