Update date&time stamp in DOS

[Spider]

I've got a number of directories (sub directories and files) I want to update the date & time stamp to now. I'm looking for something in DOS like the unix ‘touch’ command but cannot seem to find anything….Is there any way this can be easily done?

Thanks

Superb. will that traverse an entire directory tree?

Doesnt seem that Touch works for more than one file....Touch *.*, *.doc or simply * doesn't work. There are >100 files on there so cant do them individually.

Any other solution either DOS or windows based?
