Splitting exe, pdf, dll files?

Question

DLL

Hello, I have a simple question.
There is a channel (a c# application that I wrote) that can pass up to 1024 characters or char variables.
How can I split (exe, dll, pdf) into lines so that I can reassemble it later.
In the similarity, split the exe into lines after inserting it into a txt file and renaming it to exe and everything will work (this is just an example that does not work).

Something like this (I don't even know how else to ask the question).
Thank you in advance.

Convert the entire file to base64, split by 1024 characters, perform the reverse operation on the other side.
