You're going to need to set some additional flags on your call to entryInfoList():

    QFileInfoList list = d.entryInfoList(filters,
QDir::Files|QDir::Dirs|QDir::NoDot|QDir::NoDotDot);

That should get the a proper listing of the entries in the target folder.

Next, your call to push the folder onto the stack is only pushing the folder's
parent, not the folder itself:

    dirs.push(info.absolutePath());

This means that, if your target folder was X:\Temp, and you found a sub-folder
called X:\Temp\Bob, you'd be pushing "X:\Temp" onto your stack.  Probably not
what you want.  So you should change that line to instead be:

    dirs.push(info.absoluteFilePath());

After making these changes, your example recursively processes a folder as
expected.

Well, under UN*X-based systems, the permission changing should work as you
expect with setPermissions() (assuming you have sufficient rights).  Under
Windows, though, it probably won't.  Windows uses a different beast in terms
of permissions (ACLs and such), so you may need to go with a Windows-specific
solution in your code.  Look up "AllocateAndInitializeSid", "SetEntriesInAcl",
and "SetNamedSecurityInfo".
