What is a TMP file?

A TMP file is a temporary backup, cache, or other data file created automatically by a software program. It is sometimes created as an invisible file and is often deleted when the program is closed. TMP files may also be created to contain information temporarily while a new file is being generated.

More Information

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. Some programs that create and use TMP files include Microsoft Word and Apple Safari.

NOTE: TMP files are often called "temp files."

How do I open a TMP file?

Most TMP files are not meant to be opened. While you can open a TMP file in Microsoft Notepad (Windows) or another text editor, the file may not be human-readable. Typically, TMP files are deleted after either:

  • The application that created the file finishes using the file
  • You close the application that created the file
  • You shut down your PC
