OK, I see. I'll check what I can do about it.

If n/w cable is removed ....my application still runs and wait for the n/w connection and doesn't exit

Hope you got my problem

Thanks

If network cable is removed in middle, when putfiles method is transferring the file it doesn't come out from the method
