What is the File Extension TMP?
The file extension TMP refers to a temporary file. This type of file can be created by any type of program, and is usually used to store temporary information the program needs while running. Identification Temporary files can be identified by the .TMP extension after the file name. The file name itself is often nonsensical, such as a series of numbers or a string of random characters. Some programs create temporary files with extensions other than .TMP — these files usually have the tilde character at the start of their filename.
