QDir mkdir can create folder which cannot be removed

Following code will create folder called "test " which contains space in end. That causes that folder cannot be removed with Windows Explorer at all.

This happens at least in NTFS filesystem

    QDir dir(".");
    dir.mkdir("test ");

If short names are enabled then workaround to remove is use command prompt to delete this folder

dir /X
rd <SHORT NAME>

If short names are not enabled it's impossible to delete this folder in Windows.

To check that  is short names enabled. Seems that in OS drive short names are enabled but not in non OS drive by default.

If you try to do following directory from command prompt or Windows Explorer directory is created with trimmed name.
