Why can't I use the deltree command? - China DOS Union Forum

It says this is neither an external nor an internal command... What does it mean? thx

还有呢...我连sys亦不能使用..怎么会这样？thx
我的的版本是Microsoft Windows XP

There is also... I can't even use sys.. How come this is happening? thx
My version is Microsoft Windows XP

Both XP and 2000 do not support this command. You can check the help for XP.

DOS commands are divided into internal commands and external commands.

Internal commands are commands hidden inside command.com that can be interpreted and executed by command.com.
No other files (programs) (software) are needed for support.

External commands are actually other programs (files) (software) that are interpreted and executed through command.com.
However, these are standardized software provided by the DOS system, and the software names are conventional. And generally, only one command has one file. The naming of other programs (files) (software) is not specified by DOS, but is named by the software author. It is used as an enhanced software. Sometimes it may be composed of multiple files. Generally, it cannot be called an external command. But its essence is the same. There must be specific executable files, and these files must all be interpreted and executed through command.com.

I don't know if this explanation is clear enough.

Windows has not supported the use of sys since Windows Me.
(Windows Me can only transfer system files from a floppy disk to the C drive, that is, only the usage of a:\sys c:.)

deltree.exe should be said to be an external command. (At least in MSDOS 6.22, it is an external command)

In XP, the DELTREE command may have been removed. If you need it, you can add it from FREEDOS.

In the 98's C:\WINDOWS\COMMAND directory, there is DELTREE.EXE. Just copy one to XP.

In Windows XP and Windows 2000, you can use `rd` or `rmdir` instead of `deltree`.

I compiled choice with lcc and it can be used under 2000 and XP. Open the attachment

Here is the compact DELTREE command:

It's 16-bit. Is there a 32-bit one?

Agree with the opinion of the third floor.
