Force Delete a file or folder in Qt

[Arshia Aghaei]

Hi , How to force delete a file or folder using Qt ??
With administrator permissions ...

You can delete files and directories with a combination of QFile::remove(), QDir::remove() and QDir::rmdir().

If you require Windows to elevate privileges then you must use the Windows APIs to achieve that.

Not a better way ?? With a built-in function or class or struct ???

AFAIK, no. There is no object in Qt which would pop up a "password" dialog and (if answered correctly) give you root priviledges. Because some apps can do that, there should be a way of writing such object yourself. The object will depend on the operating system (windows, Linus, etc.)

[Edit] ChrisW67s link contains a way of doing it under windows.

The necessary mechansims/functions are builtin in to every copy of Windows since Vista, they are fully documented, widely used, utterly non-portable, and frankly ugly. They are, nonetheless, the better way because the alternative is that Windows stayed the wide-open malware magnet its original design made it.
