a.txt is as follows



aaaa
bbbb
dddddd
fffff
rrrrr
tttt
yyyy
uuuu
iii
aaa
dddd
ffff


For example, I want to use each line above as the name of a folder.
md %a parameter %a would be the first line. After execution, it goes back and reads again, then %a would be bbbb, and so on in turn.

With each loop, variable a becomes the content of the next line.

The for command...

Here's an example

for /f "delims=" %%i in (a.txt) do md "%%i"

Read each line in a.txt, and at the same time execute the md command,

This is a problem``
