Today I discovered that the SYS command in MS-DOS 7.x/8.0 has an undocumented /Y parameter. Does anyone know what it is used for?

Let me give it a try Wow, when typing SYS /y <drive letter> the system actually shows Cannot obtain exclusive access to drive uuuuuuuuuuuuuuuuuuuuuuuuuuu uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu To be exact, it's the Chinese pinyin "yu", that is, a u with two dots over it. And when typing SYS /y <drive1><path> <drive2> it shows, in English: not enough free disk space --<drive2> I didn't find any other problems. Please have Wengier explain.

If this is DOS's usual style, then does that mean no confirmation prompt is required when transferring system files? Strange.. I don't have a floppy disk, so I can't test it... If there is a different version of DOS on the target disk, it should give a prompt, right? Is this used to ignore that prompt? [ Last edited by fdsiuha on 2005-12-24 at 16:59 ]]]
