file_path may contain newlines, therefore you should probably use "\0" to 
separate the records. The other fields may not contain whitespace, so it's 
safe to use " " as the field separator. When you deserialize the record you 
can prevent the file_path from being broken by providing maxsplit to the 
str.split() method:

for record in"\0"):
    print(record.split(" ", 6))

Splitting into records without reading the whole data into memory left as an 
exercise ;)
