Don’t worry about it.
Actually this looks like a misleading code.

Sorry mate, I got blinded. Mistook the -del for -delete (but it's in fact -Delimiter).
Do you happen to know, if/how I can remove the previous comment?

My apologies @roba.

It does NOT remove any files, but is still something of an exploit/cheat solution (using Get-Content instead of a proper function outputting strings).

？

That's malicious code attemting to remove files. Do NOT try it on your own machine!
