How can I edit the resume file I've downloaded?

Hi, I just purchased a resume template. I’ve received 5 files in a zip folder, but I can’t seem to open and edit it. Do I need to use a specific tool? is there anything free for MAC?
I would deeply appreciate your help on this!

What are the files included? Maybe screenshot and share the folder contents?

Could you please list out files names in the zip files? so we can suggest what tools u can use to open each among them.

if you referring a html template then you have unzip the template folder and there you will get file in .html and you can use any code editor to edit the content.

You can check the template documentation to get some help.
