...... This paragraph is from an article provided in the above link...
[Occasionally, a temporary file will find its way into the root directory of
the C drive. These errant files can interfere with the computer's
operations. Every few months, you may want to click on My Computer, click on
the C: drive, and scroll down. If you see any files that end in .tmp, you
can safely delete them by highlighting and pressing the Delete key. If you
see other .tmp files while you are working on your computer, they may be the
files that are open on your computer at that time. You will not be able to
delete a temp file that is actively being used. If, however, the .tmp file
is not being currently used, you can delete it with no adverse
consequences.]
I think, but am not sure, that if you delete the entire folder, it will
replace itself...but as I said, I'm not sure.
You can also try to delete them this way, go to start>my computer>local C:
drive> right click properties>general tab>disk cleanup. Close all programs
before you do this.
