import os
# Folder to clean up — change this to your path
FOLDER = "./photos"
for i, name in enumerate(sorted(os.listdir(FOLDER)), start=1):
src = os.path.join(FOLDER, name)
if not os.path.isfile(src):
continue
ext = os.path.splitext(name)[1].lower()
dst = os.path.join(FOLDER, f"photo_{i:03d}{ext}")
os.rename(src, dst)
print(f"{name} -> {os.path.basename(dst)}")This script renames every file in a folder to photo_001, photo_002, and so on, keeping each file’s extension. Set FOLDER to your folder, then run python rename.py from a terminal.

Frequently asked questions
Is FreeCodeGen really free?
Yes — completely free, unlimited, with no signup, no credit card, and no watermark. The site is funded by ads, so it stays free for everyone.
Do I need an account?
No login, no sign-up. Just describe what you want and generate it. Nothing you type is tied to an identity.
What languages can it write?
Python, JavaScript, TypeScript, SQL, Bash, regex, HTML/CSS, Go, Java and more — 9+ in all. If you don’t name a language, it picks the most appropriate one for the task.
Will the code actually run?
It’s written to be complete and runnable, with imports and a short note on how to run it. Always read code before running it, and treat it as a strong starting point you can adjust.
Is it good for beginners?
Yes — that’s who it’s built for. Describe the task in everyday words and you get working code plus a plain-English explanation of what each part does and how to run it.
Is my prompt stored?
We log the prompt and output for abuse prevention and quality monitoring, with a hashed IP — never linked to your identity. See the Privacy page for details.
