Most likely the reason for your observation is the overhead between passing data between the QML frontend and the C++ backend that retrieves the files. When a folder is listed the backend starts doing its work and whenever new file is retrieved they're sent to the QML frontend for displaying. It's a tradeoff between responsiveness (user starts seeing results immediately instead of waiting) and total time taken. This could be improved for example by adding files in chunks instead of for each file, thus reducing the signalling overhead between QML and C++. Personally I don't think that's worth the added code complexity, but YMMV. Regards, Arto
