[postgis-users] access is denied in Windows 7

[Ulises F-Troche]

New to postgresql.

I'm using PostgreSQL 9.2 in Windows 7.  First, to be able to use psql I added the installation path in the system's environment variables. I want to know mre about pg_dump, but when running the command 

pg_dump -U postgres postgis > c:\myDump.sql

I received the error "Access is denied.".  I have 3 databases in my machine: postgres, postgis, and template_postgis_20.  User postgres is the only role and owner.

Any help on how to correctly configure this is appreciated.

Thanks
