Description
   System_WinDrives uses win32 api calls
   to get a list of all installed roots ("Drives") on the current
   Windows operating system (The folders "A:\" until "Z:\").
  
   Additional to the list of drives, detail information like 
   the name and the drive type (network, harddisk, removable etc)
   is given.
  
   The win32 api functions are used to access the Windows application
   programming interface. This means that the extension 
   php_w32api.dll on PHP4 and 
   php_ffi.dll on PHP5 have to be installed to
   use all functions. If no dll is available, the drives are guessed,
   but drive types and drive names can't be determined.
