import os
import struct
filename = str(raw_input("Please enter an old file name: "))
filenamepre = str(raw_input("Please enter an new file name prefix: "))
count = 0
filecount = 0
maxcount = 20
newfilename = repr(filecount) + '.txt'
oldfile = open(filename,'rb')
bFirst = True
while True:
s = oldfile.read(512*8 - 4)
if not s:
exit()
filecount = filecount + 1
newfilename = filenamepre + repr(filecount).zfill(2) + '.txt'
newfile = open(newfilename,'wb')
if not bFirst:
be = 0XFEFF
newfile.write(struct.pack('H',be))
newfile.write(s)
be = 0X000A000D
newfile.write(struct.pack('I',be))
newfile.close()
bFirst = False
oldfile.close()
