Copy and move

when copying,it does not automatically number files ,when names clash

The "Rename New" option will do that if you choose it when prompted.

yes,i have seen that,but was wondering,if you would have that in a setting and it become automatic;kindly respond

The Copy command has a WHENEXISTS argument for that:!Documents/Copy.htm

With Opus Light, you can't change the Copy Files button on the default toolbar or change what happens when you drag & drop, but you could make a special button on a custom toolbar which uses the argument, for when you know you want to auto-rename things. (It's probably best not to change the normal behavior anyway, since you could easily rename something you didn't expect to exist if you did.)
