Answer 1

This works for me, but I think you may need to provide more information.
Like...
What you want the filenames to be?
What you know about the data
For example, do you always want to split on lines that start with HC? Are the values in the first column always going to be in the form HC#####?
Making a few assumptions, this is a basic example of what you could do.
This will iterate through every line in the file. If the line starts with HC#####, then it outputs that line and every following line to a file with that name. When it reaches a new HC##### value, it changes that to the file name:
$data = Get-Content .\sample.txt
foreach ($line in $data) {
if ($line -match '^HC[0-9]+') {
$fileName = "$($Matches[0]).txt"
}
Add-Content -Value $line -Path $fileName
}
This is assuming the first line will always provide us a filename.
It's also assuming that you want to split on lines starting with HC
It's also not performing any sort of exception handling.
