DeleteFile() is a Win32 API and has nothing to do with Linux devices.
I also ment to state that I can hapilly open, position and read these devices with CreateFile()/SetFilePointer()/ReadFile(), it's only when FILE_FLAG_DELETE_ON_CLOSE is specified there is a problem with CreateFile() which is probably why DeleteFile() fails.
