New Post: File uploading more than Once

Hi Everyone,

I am using rencissh.net dll to upload file to particular location,
As soon as file got uploaded different thread will pick up the file and delete, and it will start process with in span of a second.
in that span of time file is getting uploaded once again.

How can i avoid uploading of file twice?
Is there any property i need to disable in renci?

Please help me in this.
