Why does Excel and Power create lock files and Word does not?

[Andrew Meinolf]

Why does Excel and Power create lock files when you open a file and Word does
not? We have a location on the network in which user have file creation
rights but do not have delete rights. So what happens now is the user open up
Excel or PowerPoint it creates the lock file example: ~$test with auto
save.xlsx. The files stay out there and never get deleted unless manually
from the server side. When a user opens a Word document the files are not
created. I want to know why? Is there a way to turn the lock file creation
off?

Word do this also. Perhaps you have set the Word documents to be cached
locally?
