Delete line from text file

I have a text file that’s generated by an app, and I want to limit the length by deleting the oldest (i.e. first) like whenever the file grows to 100 lines to keep it from getting too huge.

Other than reading the file into a variable, deleting the line, and re-writing the entire file, is there a better way to just delete the first line of the file?

In *nix you could use an operation like “cat” to output the last part of the file and then “redirect” it to another file.

Unfortunately for me, work = Windows, so that’s a no go.
