thanks - I've been searching a while for how to remove the "generated by...."

so I get that should put
file:///.+(\d|(txt|html|htm))
into preferences structure detection, but what happens to the default expression that's already in there ( which I don't really understand).

do I overwrite it with the above, and if, so what do I lose i.e. what was the default expression doing that yours may not do ?
