Is it safe to delete temp files and folders?

[John]

My norton antivirus hangs up on my wife's temp file
folder. Is it safe to go into C drive and delete all
folders and files inside the Local Settings/temp folder
under her user area? Symantec suggested that but there
are quite a few folders there. I would like to think that
any important folders and files just get recreated when
the need next arises but not sure.

They should be just fine to delete.

Yes. They can, and should be, deleted periodically. You can
safely delete anything except those in use, but since Windows
won't let you delete a file in use, it's safe to try to delete
them all.
Just don't delete them automatically as soon as you boot. That
can screw up program installations that work in two steps--the
first step ending by saving temp files and rebooting; the second
step needing to find those temp files when the boot completes.
