Thanks.  I'll try, but it doesn't seem the same.

In my case, the initial download finish successfully 
but a few files may failed due to occasional network 
problem.  If you have used Teleport Pro, there's an 
option called "Retry Broken Links Only".  With this 
option, the project will only retry the failed (say 
100) files, instead of testing thousands files to see 
which have been changed.

Anything similar here?
