TMP file format

A tmp file with that ending is a type that is used as a temporary solution. They occur more frequently in the installation of a program. These temporary are created and stored until the program has completely installed all its applications.


Storage information

These  are used to store things in the programs before the information is stored correctly. For example, if you are writing something in Microsoft Word, it will be saved on the computer as a .tmp file until it is saved manually with a name and a .doc. Although most can not be opened in reality, one created for a Word document can usually be opened in that same program.



A type of .tmp has no effect on the execution of a program once it has been installed. It is only during the installation that some applications use the temporary files to prevent the memory of the operating system from becoming saturated.



Files with tmp format can be found on Windows, Macintosh and Linux operating systems. Some installation programs will delete temporary objects when they are finished. While others will leave them on the computer until they are manually deleted.



Although the temporal do not damage a computer, there have been memory resident viruses created with that format. There are also times when these are still being used by a system that has not completed the installation.

Do not open or delete one with this format before know where it comes from and what it does.
