I am buidling a tool that will check in ArcPad data (using check in tool) and then delete the files from the hard disk. 

The problem is the delete operation always executes first deleting the files before they can be checked in.

The Check in tool has no output so I can't set a precondtion. Is there anyway I can force the checkin to happen before the delete?

I am attaching a picture of the model with hand drawn depection of the problem.
