Split a file or an archive in chunks

Requirements

Linux OR
WSL

Steps

Have a directory with your file. In our case file.7z

folder/
  file.7z

In terminal

split -b 2000M file.7z file_

This will create 2GB files named file_aa, file_bb and so on

To build back your file.7z in your folder with your pieces like this

ls folder

folder/
  file_aa
  file_ab

just type

cat file_* > file.7z
