Wildcard
Wildcard can use * (string mode) and ? (one character).
Wildcard only apply to kill (delete of document) and fcopy (copy of document) command.
We can't use wildcard in the catalog. (Can't apoint to"/c0/*/*.bmp"such form)
We needn't take note of catalog that to be in wildcard object. (Apoint to kill "/c0/img/*", "/c0/img/capture/"catalog will not be deleted)
