This is the code what i use to save the file.
tmpData = str(rawData)[1:].strip("' '")
tmp = tmpData.split('\\r')
for piece in tmp:
for slice in piece.split('\n'):
if 'Content-Disposition' in slice:
filename = slice.split(';')[2].split('=')[1]
h = open('home/hidura/'+filename.strip('" "'), 'wb')
elif '\\x' in slice:
pickle.dump(slice, h)
h.close()
