I Mined My Google Drive With 50 Lines Of Python And Found 13 Projects I Forgot I Built

I've had a Google account since 2016. Drive has been the graveyard where every half-finished side project, every "I'll come back to this" folder, every client handoff, and every screenshot of a whiteboard goes to die. I had 8,400 files in there last week and no idea what was in most of them.

So I wrote 50 lines of Python to walk the whole thing, classify it, and tell me what I had. I expected to find a mess. I did not expect to find 13 fully-functional projects I had completely forgotten about, including a working Discord bot from 2019 that I had apparently deployed to somebody's server and never shut down. (It's still running. It has 240 users. I had no memory of this.)

Here's the script, the gotchas, and what I found.

Step 1: OAuth for Desktop apps (not the web flow)

Every Drive API tutorial online uses the web OAuth flow, which requires you to host a redirect URI. For a one-off script running on your laptop, that's insane. Use the Desktop app flow instead, which runs a local HTTP server on a random port for the redirect.

Go to console.cloud.google.com, create a project, and this is where the first gotcha lives:

Gotcha #1: Drive API not enabled

When you create a new GCP project, the Drive API is not enabled by default. It's not even listed on the main dashboard. You have to go to "APIs & Services" → "Library", search for "Google Drive API", and click Enable. If you skip this step, your script will fail with a cryptic 403 that says "Google Drive API has not been used in project X before or it is disabled", and it'll give you a URL to enable it. Click the URL. Wait 90 seconds for it to propagate. Then try again.

Then create an OAuth 2.0 Client ID, and critically, pick "Desktop app" as the application type. Download the JSON file it gives you and save it as client_secrets.json next to your script.

That file is what the google-auth-oauthlib library will use to launch your browser, have you approve, and drop a token into your local server.

Step 2: the script

Install the dependencies:

pip install google-auth google-auth-oauthlib google-api-python-client
Enter fullscreen mode Exit fullscreen mode

And here's the whole thing:

import os
import json
import pickle
from pathlib import Path
from google.auth.transport.requests import Request
from google_auth_oauthlib.flow import InstalledAppFlow
from googleapiclient.discovery import build

SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly']
TOKEN = Path('token.pickle')
SECRETS = Path('client_secrets.json')

def get_service():
    creds = None
    if TOKEN.exists():
        creds = pickle.loads(TOKEN.read_bytes())
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
            creds.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(str(SECRETS), SCOPES)
            creds = flow.run_local_server(port=0)
        TOKEN.write_bytes(pickle.dumps(creds))
    return build('drive', 'v3', credentials=creds)

def walk_all_files(svc):
    """Yield every file in the account, paginated."""
    page_token = None
    while True:
        resp = svc.files().list(
            q="trashed=false",
            pageSize=1000,
            fields=(
                "nextPageToken, files(id, name, mimeType, size, "
                "modifiedTime, createdTime, parents, webViewLink)"
            ),
            pageToken=page_token,
        ).execute()
        for f in resp.get('files', []):
            yield f
        page_token = resp.get('nextPageToken')
        if not page_token:
            return

def build_path_index(files: list[dict]) -> dict[str, str]:
    """Reconstruct folder paths from the flat file list."""
    by_id = {f['id']: f for f in files}
    cache = {}

    def resolve(fid: str) -> str:
        if fid in cache:
            return cache[fid]
        f = by_id.get(fid)
        if not f:
            cache[fid] = ''
            return ''
        parents = f.get('parents', [])
        if not parents:
            p = f['name']
        else:
            p = f"{resolve(parents[0])}/{f['name']}"
        cache[fid] = p
        return p

    return {f['id']: resolve(f['id']) for f in files}

if __name__ == '__main__':
    svc = get_service()
    print('Walking Drive...')
    files = list(walk_all_files(svc))
    print(f'Found {len(files)} files')

    paths = build_path_index(files)

    # Dump to JSONL for downstream analysis
    with open('drive_inventory.jsonl', 'w') as out:
        for f in files:
            f['path'] = paths.get(f['id'], '')
            out.write(json.dumps(f) + '\n')
    print('Wrote drive_inventory.jsonl')
Enter fullscreen mode Exit fullscreen mode

That's 50 lines (give or take imports). First run, it'll pop a browser tab, you approve, it writes a token.pickle, and every subsequent run uses the refresh token automatically.

Gotcha #2: Drive is flat, paths are fake

The thing that tripped me up for an hour: Google Drive doesn't have real folder paths. Internally, everything is a "file" (including folders, which have mimeType: application/vnd.google-apps.folder), and each file has a parents array listing its parent folder IDs.

There is no path field. There is no endpoint that returns a path. If you want a human-readable path, you have to reconstruct it yourself by walking up the parents chain recursively. That's what build_path_index does in the script above.

A couple of subtleties:

  • Files can have multiple parents (if they were added to multiple folders before Google phased that out). I just pick parents[0].
  • Files can have no parents at all if they're in the root or have been orphaned. I treat those as top-level.
  • Circular parent chains are technically possible if someone has done something horrible. I didn't handle this because it never happened in my Drive, but if you're paranoid, add a visited set.

The recursive resolution with memoization means even on 8,400 files it runs in under a second.

Gotcha #3: pageSize=1000 is the max

The Drive API caps pageSize at 1000. If you ask for 5000 it silently gives you 100 (the default) and you spend 20 minutes wondering why you only have 100 files.

Always specify pageSize=1000, always use the nextPageToken pagination loop. On 8,400 files that's 9 API calls, which takes about 4 seconds total.

What I actually found

Once I had drive_inventory.jsonl, I loaded it into a one-off notebook and did some basic classification:

import json
from collections import Counter

files = [json.loads(l) for l in open('drive_inventory.jsonl')]

# How many of each mime type?
mime_counts = Counter(f['mimeType'] for f in files)
for mime, n in mime_counts.most_common(15):
    print(f'{n:5}  {mime}')

# How many folders look like projects?
project_like = [
    f for f in files
    if f['mimeType'] == 'application/vnd.google-apps.folder'
    and any(kw in f['name'].lower() for kw in ['project', 'app', 'bot', 'tool', 'v1', 'v2'])
]
print(f'\n{len(project_like)} folders look project-ish')
for f in project_like:
    print(f"  {f['path']}")
Enter fullscreen mode Exit fullscreen mode

This is where things got wild:

  • 2,341 images I had no memory of uploading
  • 413 PDFs, half of them textbooks from grad school I don't need anymore
  • 89 .ipynb notebooks from old side projects
  • 13 folders containing actual complete projects with source code, README files, and deploy scripts

The 13 forgotten projects included:

  1. A Discord bot that's still running on somebody's server (seriously, this is how I found out)
  2. A Chrome extension I built in 2020 for summarizing Hacker News threads
  3. A React weather app with a finished frontend and no backend
  4. An Android app I started for tracking climbing sessions
  5. A Python CLI tool for generating D&D encounter tables
  6. A half-finished Rust ray tracer
  7. Three separate Jekyll blogs, each with 2-3 posts
  8. A working Slack bot for a team that doesn't exist anymore
  9. A scraper for tracking used bike prices
  10. A Pygame platformer my younger sister and I built in an afternoon

I am now working through a "revive or bury" review of the 13. Two of them are legitimately good ideas that I'll reboot. Five are going straight into the grave. The rest I'm not sure about yet.

The meta-lesson

Every long-running software person has this pile. Drive, Dropbox, a dozen external hard drives, a GitHub account with 200 abandoned repos. We build far more than we remember. The difference between "stuff I built" and "portfolio" is usually just whether you wrote 50 lines of Python to go look.

If you have an account that's older than 5 years and you've never done this, I cannot recommend it enough. You will find at least one thing that makes you say "oh my god I forgot about that, that was actually good."

The script I use for this is part of a small collection of "audit your own digital life" tools I'm building as agent actions. If you want to run the same kind of inventory on your Gmail, Calendar, Photos, or GitHub, the pipeline I'm putting together is at whoffagents.com.
