Question : Is it important to delete WRL files

When I view hidden files, I see that the directory where I keep all of my Word files has many files that begin with ~WRL, such as ~WRL0190.tmp

It has these files even when I have no Word files open.

Should I delete these files? if you say I should, do you mean I should do it to save space, or because these files will do harm to a Word file I open up in the future? (if the latter, that would mean that every so often I should set my computer up to view hidden files and then delete all such files)

Thank you

P.S. I'm running Word 97 on a windows 98SE computer  

Answer : Is it important to delete WRL files

Usually it should not happen.
Those are usually ur "last saved verision before ur windows/word crash"
Thus, i feel it is safe to delete.

Thats what i feel... maybe u wanna wait to see if any experts have any opinion about it.. ;)
