DOS Sort+Add Sequence number+Remove Sequence number

#1
Hi

I want to edit a folder with 3500 .wma music files(records). Can someone please give me the exact DOS CMD Commands to -
a) Sort the folder alphabetically
b) Add a Sequence number in front of each music record's filename
(at this point I want to edit the folder's records - remove, repair and load back the one's with problems)
c) Remove the Sequence numbers

Thank-you very much

Hennie

for /f %fn in (wma.lst) (ren "%fn" "%[num]%[fn]" & set /a %num=%num + 1 )
3)
