`man split` is your friend.

Try: split -l 5000 --additional-suffix=.csv /desktop/ESM.csv 
/desktop/ESM.csv ESM

(all in one line)

It means split ... with resulting prefix "ESM", and suffix ".csv").

The command you show has default prefix x, no sufix, then the result 
should have been xaa, xab, xac, etc.
