WHAT ARE TEMPORARY FILES?
Temporary files are created temporarily by programs that store information related to the file you are working on
in your computer. It increases the efficiency of the software and also helps in recovering the data at the time of
unexpected closing of the file due to power failure or system shut down.
Temporary files are deleted automatically when the task or program you have been working on is completed. If all the
programs in a computer are closed and temporary files still exist then look for files with the extension .tmp in the folder
TEMP. They are of no use and they block a lot of disk space. It is better to delete them as they hinder the performance
of your computer. If the deleted temporary file is required by the program again then it is automatically recreated
without affecting your programs.
