File system utility with more functions than QDir

[izico]

What is wrong with QDir::rename()?

when newName and oldName are in different partions,QDir::rename(oldname, newName) will hang(at least on one of my system). So I can't use simple if (!rename()) { copy(); remove()};(this works in Posix rename(),as it returns error quickly) I must find a portable way to know if the two are in different partitions,and I find no portable way to do this by now.
Any good idea about this?

You could use a dir model, but there is no guarantee if you symlink directories. Maybe the problem with rename() is a problem with your system and not the actual rename?

I just checked Qt sources and it looks like Qt simply performs a copy and delete of the file in question. So the only slowdowns could be caused by performing the copy or finding filepaths.
