No.

That will trigger all the stuff in 10 seconds. You'll want to use:

/timer 1 $calc(10*1)
/timer 1 $calc(10*2)
/timer 1 $calc(10*3)

and so on.

also, this else statement is not needed:

Code:
else { goto checkfolders }
:checkfolders


Regardless of the else statement, it will drop down to the :checkfolders line.

If you want to test this, just try:
Code:
alias testing {
:start
echo -s start
:body
echo -s body
:end
echo -s end
}
