In know, that .opdownload is unfinished download. In Java I have WatchService and after download begins, service give me path to two files - one with .opdownload extension and one with "normal" extension (so it looks like file I'm looking for, but file is empty, doesn't have modification time etc. - it looks like Opera only create path to this file). Then after download finishes service give me third path to downloaded file.

Sorry, I didn't make myself clear - when debugging my app I see, that three entries are created as described above.

Hello.

I use Opera for saving file and then I need to process this file. I look up for new entries in given directory and I see three entries - first one is empty file, with normal file name, second one is file with ".opdownload" extension and third one is file with normal file name and non-empty content.

My question is - why Opera creates first entry, just after download begins? Or maybe I don't understand something in Window's file system?
