That doesn't make a lot of sense to me.
Can you supply some examples of what you want to match and not match?
Does the expression given match the one example you gave in the language
you are using or not? (it would in perl).
Could you let us know exactly which regex engine you are using?

For Example:-
String :- ftp:\\abnssjs%20jfdhjdh.htc%00.mnd
Match :- ftp:\\abnssjs%20jfdhjdh.htc%00. (What i want)
String :- ftp:\\abnssjs%20jfdhjdh.ads%00.htc%00.exe
Match :- ftp:\\abnssjs%20jfdhjdh.ads%00. (What i want)
I am trying this on application supporting pcre library of http://www.pcre.org/

OK in perl you would specify lazy matching:
/ftp:.*?%00\./
and if you want to capture what matches (rather than just affirm a match):
/(ftp:.*?%00\.)/
