Splitting when a line begins with a specific character

My colleague has to regularly split a large log file (in notepad - approx 12MB) into smaller files.

See below for a compact example of the document structure

The large file is split wherever a new line begins with “A”.
The same header and footer is then inserted to each small file.

So, our first ‘split’ file from the example above would look like this.

I feel that the ‘split after the nth occurrence of a specified pattern’ tool should allow us to do this but I do not understand how it works.

If someone is able to tell me how to do this (using a version of the “0x0D0x0A” pattern I presume) that would be greatly appreciated!

I understand how to add a header and will figure out how to handle the footer.

Thanks!

The pattern 0x0D0x0A means two characters named CR LF

See:

So if you want to split after a new line and the A character that begins next line, you should use this pattern:

0x0D0x0AA
