How to detect if a file is being used ?

[Extreme]

Hello !

With QM i've programmed a macro that scans a specific folder for specific files, and then move then to another specific folder.

Exemple : QM scans D:\Folder1-> QM Detects a new file in D:\Folder1-> It moves it automatically to D:\Folder2

The issue here is that when files are being downloaded to D:\Folder1 , they are obviously used by another process for the download ( chrome, bitorrent... ) so they can't be moved, and i can't figure how QM can detect this.

The ideal solution would be :

QM scans D:\Folder1-> QM Detects a new file that is not used by any process in D:\Folder1-> It moves it automatically to D:\Folder2

Is there a clean way to do this ?

Thanks !
