Thread Subject: clearing text files

I'm getting matlab to write some text to a txt file but I want it first to remove anything that's already in that text file .. so that it's clear before I start writing. Can matlab do this ?/

If you use:
fid=fopen(txtfile,'wt');
the 'wt' will do it for you automatically.
