the Windows API SHChangeNotifyRegister can detect file creation in disk, but how to know if ‘file creation’ is caused by file copy or not? thank you!
[EDITED], I mean SHChangeNotifyRegister, but not SHChangeNotify, sorry!
If you know the file name which is changed you can examine it’s creation and last write times with respect of GetFileTime. If you copy a file from one directory to another you don’t modify the file contain, so the last write times will stay unchanged.
