At BAT file programming i wanted to find a file and delete it then goto a page..? Answered

at BAT file programming i wanted to find a file and delete it then goto a preffered page..

i've found:
if example.file exists goto a
if example.file does not exist goto b

but it's only for a single file, doesn't search the whole drive or pc.

i've found:
dir C:\example.file \s

this thing searches whole C drive,
but how to make it to go to a preferred page??
any way??
very very thanks in ADVANCE.. :D
