Alternatively (no piping):

Xy3:
 DOS /C KMD.EXE /C DEL /Q [d:\path\]*.*
Xy4:
 DOS/NV/Z /C KMD.EXE /C DEL /Q [d:\path\]*.*

"Exit" is inherent in "DOS /C" -- shell to DOS, and issue
one command. If you don't wish to exit, execute KMD /K
instead of KMD /C:

Xy4:
 DOS/NV /C KMD.EXE /K [command1 & command2 & ...]

That would issue the specified command[s] (or no command)
and remain at a command prompt until you issued "Exit", to
return to XyWrite.

DELTREE is bundled with W98, but not NT (nor W95, IIRC). Two solutions:
DELTREE.CMD, which is part of XyShell; or the much-enhanced RMDIR|RD command
which is part of NT (and, by virtue of KMD.EXE, available in 9x also), e.g.:

Xy4:
 DOS/NV/Z /C KMD/C RD/S/Q [d:]\path
