One moment...if i understand right, you mean something like first creating a "memory snapshot" of the content of the current-dir, putting all node-items in a list/queue, than processing the queue... if so, that is a really nice idea... 
it could be the right solution... Thanks a lot, hopcode . . . |

The pseudocode for such an implementation is pretty simple - implementing it efficiently is left as an exercise for the reader
 . It doesn't have to be insanely efficient since you're I/O rather than CPU-bound, and normal systems won't have huge amounts of entries in a folder, nor super deeply nested. Still, it's fun to optimize things, isn't it?
Code: listfiles(startpath,mask,callback) { queue dirqueue; //queue is a FIFO structure: push_back() and pop_front(). dirqueue.push_back(startpath); while(!dirqueue.empty()) { currentpath = dirqueue.pop_front(); foreach(entry in getentries(currentpath, mask)) if(entry.isdir && !entry.isjunction) dirqueue.push_back(entry); // folder, proces later else callback(entry); // file, give to callback } } |

I always liked the idea of getting an entire directory's entries first, then iterating. Helps with caching I thought...
