Use cvs import
In WinCVS, email clicks on the directory you want to add (for example, called Mycode), select Import Module
Then select Module Name, knock in the path to which directory you want to put under.
For example, there is a module called NewSRC, and you always enter this every time you checkout all the code.
You want to put in NewsRC / AAA / BBB / MyCode.
Then enter newsrc / aaa / bbb / mycode is ok.
This is to do this, all files under the local mycode are uploaded to the CVS server, and the MyCode folder is created on the server.
