.TMP File Extension

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.

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."

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

File created by Finale, a music notation program for instruments, vocals, and more; contains backup data for the document you're working on; acts similar to a cache file; exists only while you're working in Finale and deleted when the program is closed; cannot be opened manually.

NOTE: You cannot manually create a TMP file in Finale and you'll most likely never see one.
