Question

why i cant create a folder which name is "con"??plz give me an explanation....

Answer 1

you might already have a folder named that. just a guess its happen to me.

Answer 2

You can't create foldeer named "con" because this comes under the category of certain reserved file name for "Ms-Dos" .This files are reserved for certain fix task while the operating system was made,so you can,t use folder names like
PRN
AUX
NUL
CON.- incidentally was a device file used to capture whatever was printed onscreen.
But if you want to create you can do it with the help of cmd prmt.
I hope now it is clear to you...

Answer 3

con is a reserverd word...

Answer 4

reserved word means???

Answer 5

Hello;
As they said, those words : CON, NUL, PRN .... and so on are considered as reserved words.
By backway to the DOS 1.0, they were used (CON,...) by users to prevent the assembler from creating a ".lst" file, they do that for many reasons maybe because they haven't enough space! I will give you an example :
*Notice that DOS 1.0 didn't support lowercase, and subdirectories!*
You have a file called "ktob.asm" and you run the assembler so the result will be as follow :
**************************************************
User > asm ktob.asm
Source file: KTOB.ASM
Listing file [KTOB.LST]: For default hit enter
Object file [KTOB.OBJ]: For default hit enter
*************************************************
Here you see the assembler create automatically a file called "KTOB.LST" in the disk of course. Suppose you don't want this file to be created in the disk, what would you do ?!

So when the assembler asks you for the Listing file name, you can enter for example CON, which means "don't write the output in a file named "KTOB.LST", instead, write the output directly to the Screen (CON, means screen).

And as the DOS is still used in the actual systems for some reasons so you can't rename your files and folders with those names.

Hope that help you in a way or another. Thanks and have a nice time.
