Random File Name Generator

What this tool does

This tool generates realistic file names on demand, drawn from a built-in list that spans documents, code, images, media, archives, and config files. Set how many you want, optionally narrow them with a few filters, and it hands you a set of plausible names in a click.

How to use it

1. Set the quantity of names you want.
2. Optionally filter the results: Starts with, Contains, or Ends with a piece of text.
3. Press Generate, then Copy the names you want.

How it works

The tool draws at random from a curated list of believable file names, the kind you would actually find on a real computer, like Project_Plan.docx, main.py, or Screenshot_2025-10-17.png. The filters narrow that list before it picks: "Starts with" and "Ends with" match the beginning and end of the name, and "Contains" matches anywhere inside it, all ignoring case. So filtering by an ending like .csv is a quick way to get names of a particular file type.

What it is good for

This is a small tool that quietly saves a surprising amount of fiddling. When you are building or testing something, you often need plausible file names without wanting to invent them one by one: populating test data or a mock file listing, filling in placeholder names for a screenshot, demo, or tutorial, or seeding examples in documentation. Realistic names make those mock-ups look convincing in a way that file1, file2, file3 never does. It can also simply nudge you when you are stuck naming something real. One thing to keep in mind is that the names come from a built-in list rather than endless invented combinations, so a very narrow filter may return only a handful, or none at all, in which case loosen the filter. To bundle files together there is the Zip Creator, and to check a real file's details, the File Inspector.
