Thanks, I guess using official command is the best. Following your examples
I did one on my own. Still using savesome though. 
 
forvalues i=500 1000 to 5000 {
local a=`i'- 499
savesome x in `a'/`i' using "somepath\list`a'to`i'"
}

Here is a solution that uses only official Stata commands:

forvalues f = 1/10 {
	preserve
	keep if inrange(_n, (`f'-1)*500 + 1, `f'*500)
	save file_`f'
	restore
}
