Hi Jean-René,

>I need to format a disk in the drive a:\. I do not want to use the DOS format from VFP with the run command.

The following API call would display the Windows standard format dialog:

Set Library To FoxTools Additive
Declare Integer SHFormatDrive in Shell32.DLL ;
   Integer HWND, Integer Drive, Integer FmtID, Integer Options
SHFormatDrive( _WhToHwnd(_WMainWind()), 0, 0xFFFF,0)
