This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.

Forgive me if you have already looked into this issue, but it seems to me that this might not be a good application for multi-threading. If all the files are on the same file system, then checking for lots of files "all at once" may not achieve improved performance.

Sorry if i didn't explain myself very well.
The thread will target a file checking class that will loop through the file definitions until all files have been received.

The logic I showed above would do the trick if each task looped inside its run method until the file existed. But it would be overkill. You don't need a thread per file, just one thread for the checker. Here's a possibility not quite in Java ...
At any moment the collection contains a list of files not yet found if anybody else is interested. You might have to synchronize any get on the remaining list.
