Split a .txt into other .txt through the identifier at the beginning of the line

I'm trying to split a file into smaller files, I'm getting via serversocket a file and I want this file to be divided according to the identifier that comes at the beginning of each line, I have this code so far, I can write some of the files, but the content is not coming correctly, here is an example of the .txt file.
