Based on this comment, I assume you wish to create a batch file that will toggle the hidden state depending on the current state.
Based on your example, I assume you want to set it to both hidden and system if it is not hidden nor system at the moment, and if either one is set then clear both.
@echo off
set _folder="Foldername"
dir /a:h %_folder%>nul 2>nul
if %errorlevel%==0 goto clear
dir /a:s %_folder%>nul 2>nul
if %errorlevel%==0 goto clear
attrib +h +s %_folder%
exit /b
:clear
attrib -h -s %_folder%
exit /b
Ok, I'll explain this step by step.
@echo off prevents output from showing up
Using the _folder variable makes it easier to change the name. You could also set it to %*, meaning all parameters passed to the batch file, which can then be used like so: batchfile.bat path_to_folder
The dir command is used to determine if the folder is hidden, then if it is marked system. In each case, It searches for the folder with filtering so only those with the appropriate attribute set are found. If it can find the folder with that attribute filter, errorlevel is set to 0. Otherwise it is 1. >nul 2>nul prevents stdout and stderr output.
If it can find that either the hidden or system attribute is set, it jumps (goto) the :clear label, where those attributes are unset.
If it can't find those attributes set, it sets both of them.
