ZincBundleCloneTask leaves Documents directory with double the files

[marksands]

In createBundleLinksForManifest: in ZincBundleCloneTask.m, I noticed the file manager calls linkItemAtPath:toPath:error, which leaves a copy of the asset in the objects directory and a copy in the bundle directory thus taking up twice the storage space.

Any compelling reason why this is preferred over moveItemAtPath:toPath:error:? I assumed it was for caching purposes if the network was interrupted during the cloning, but I didn't see a cleanup task being performed after the clone was complete. I'll admit I didn't dive too far into the code, but at first glance I was wondering what the preferred way to clean up directory was?
