@JonB no... It will return the directory where new file added or renamed or removed.. Not the path for newly added file.. Correct me if I am wrong

Hi,

If you need that level of details, may QFileSystemModel would be more interesting. You can use the rowsInserted signal to grab the information you are after.

Otherwise, you should keep a list of the entries of the folder you are watching in order to compare it to it's new content when directoryChanged is called.

QFileSystemWatcher::directoryChanged signal is as good as it gets :) You have to figure out what got added. I'm not sure whether @SGaist is saying QFileSystemModel::rowsInserted can be used to automatically monitor changes in the background.
