When file is too large, we will compress it and split it into several parts.
Now Let me show you how to combine them in Linux command line.
step 1: Install rar command
sudo apt-get install rar
sudo apt-get install p7zip-full
step 2: Merge rar files
rar e filename.rar
7z e filename.7z.001 -tiso.split # split will tell 7z that package is splitted
For example:
