## PART 1 — Immediate Cleanup (Safe to Delete)
**Estimated savings: ~18–22 GB — no data loss**

### Step 1: Empty the Trash (1.3 GB)
```bash
rm -rf ~/.local/share/Trash/files/*
rm -rf ~/.local/share/Trash/info/*
```

### Step 2: Delete Chrome's AI Optimization Model (4 GB!)
Chrome downloads a machine-learning model to optimize page loading. It **rebuilds itself automatically** the next time Chrome runs — you lose nothing permanent.
```bash
rm -rf ~/.config/google-chrome/OptGuideOnDeviceModel
```

### Step 3: Clear All Browser Caches (~5.5 GB)
Browsers rebuild their cache as you browse. You may notice slightly slower page loads for a day or two.
```bash
rm -rf ~/.cache/BraveSoftware/Brave-Browser/Default/Cache
rm -rf ~/.cache/google-chrome/Default/Cache
rm -rf ~/.cache/google-chrome/"Profile 1"/Cache
rm -rf ~/.cache/google-chrome/"Profile 2"/Cache
rm -rf ~/.cache/mozilla/firefox/*.default-release/cache2
rm -rf ~/.cache/browser-os/*/Cache
```

### Step 4: Clear Package Manager Caches (~1.8 GB)
```bash
sudo apt clean                   # APT downloaded .deb files (610 MB)
rm -rf ~/.cache/uv               # Python uv cache (638 MB)
rm -rf ~/.cache/node-gyp         # Node build cache (120 MB)
npm cache clean --force          # npm cache (part of ~/.npm)
rm -rf ~/.cache/go-build         # Go build cache (77 MB)
```

### Step 5: Trim System Journal Logs (saves ~2.4 GB)
Linux keeps a rolling log of everything happening on the system. 2.9 GB is excessive — capping it at 500 MB still keeps plenty of history for troubleshooting.
```bash
sudo journalctl --vacuum-size=500M
```

### Step 6: Clear Thumbnail Cache (~404 MB)
These are small preview images for your file manager. They regenerate automatically when you browse folders.
```bash
rm -rf ~/.cache/thumbnails/*
```

### Step 7: Remove Unused Flatpak Runtimes (~1–3 GB)
Flatpak keeps old runtime versions even after apps are updated. This command removes anything nothing depends on anymore.
```bash
flatpak uninstall --unused
```

### Step 8: Clear Playwright Test Browser Cache (~128 MB)
```bash
rm -rf ~/.cache/ms-playwright-go
```

### Step 9: Clear Gemini Temp Files (~64 MB)
```bash
rm -rf ~/.gemini/tmp/*
```

## PART 2 — Move Data to the 14TB Drive
**Estimated freed from OS drive: ~20 GB**

The strategy here is: move the folder to the 14TB drive, then create a **symlink** at the original location. Think of a symlink like a Windows shortcut — when a program goes looking for `~/Downloads`, Linux silently redirects it to the real folder on the 14TB drive. The program never knows anything changed.

> **Before running any move command**, make sure the 14TB is mounted:  
> `ls /mnt/14TB-HD` — you should see files listed, not an empty folder.

### Move 1: Downloads Folder (6.9 GB)
```bash
mv ~/Downloads /mnt/14TB-HD/Downloads
ln -s /mnt/14TB-HD/Downloads ~/Downloads
```

### Move 2: Debian ISOs (5.0 GB)
These are just old installation images — move them to the 14TB for archiving, or delete if you no longer need them.
```bash
mv ~/debian-iso /mnt/14TB-HD/debian-iso
```

### Move 3: FreeDOS Custom Build (423 MB)
```bash
mv ~/freedos-custom /mnt/14TB-HD/freedos-custom
```

### Move 4: DigiKam Photo Database (5.5 GB)
DigiKam (your photo manager) stores its face recognition engine and metadata database in your home folder. Moving it to the 14TB frees up 5.5 GB.
```bash
mv ~/.local/share/digikam /mnt/14TB-HD/digikam-db
ln -s /mnt/14TB-HD/digikam-db ~/.local/share/digikam
```
After moving, open DigiKam and go to **Settings → Configure DigiKam → Database** to confirm it still sees the database correctly.

### Move 5: Frigate Config & Data (913 MB)
If Frigate is running, stop it first so files aren't in use:
```bash
sudo systemctl stop frigate      # stop the service first
sudo mv /opt/frigate /mnt/14TB-HD/frigate
sudo ln -s /mnt/14TB-HD/frigate /opt/frigate
sudo systemctl start frigate
```

### Move 6: VS Code Extensions (1.9 GB — optional)
```bash
mv ~/.vscode /mnt/14TB-HD/vscode
ln -s /mnt/14TB-HD/vscode ~/.vscode
```

## PART 3 — Change Default Save Locations in Programs

### All Browsers — Change Download Folder
Set each browser's download location to `/mnt/14TB-HD/Downloads` so new downloads go there automatically:
- **Brave:** Settings → Downloads → Location
- **Chrome:** Settings → Downloads → Location  
- **Firefox:** Settings → General → Downloads → Save files to

### System-Wide Default Download Location
This tells all XDG-aware Linux apps (file manager, etc.) where the Downloads folder is:
```bash
nano ~/.config/user-dirs.dirs
# Find this line:
#   XDG_DOWNLOAD_DIR="$HOME/Downloads"
# Change it to:
#   XDG_DOWNLOAD_DIR="/mnt/14TB-HD/Downloads"
# Save with Ctrl+O, then Ctrl+X to exit
```

## Summary: Expected Space Recovered

| Action | Estimated Savings |
|---|---|
| Empty Trash | 1.3 GB |
| Chrome AI model (OptGuide) | 4.0 GB |
| Browser caches (all) | 5.5 GB |
| Package manager caches | 1.8 GB |
| Journal logs (trim to 500 MB) | 2.4 GB |
| Thumbnail cache | 404 MB |
| Flatpak unused runtimes | ~1–3 GB |
| Gemini temp + Playwright cache | ~192 MB |
| **Total cleanup (no data loss)** | **~18–22 GB** |
| Move Downloads to 14TB | 6.9 GB |
| Move debian-iso + freedos to 14TB | 5.4 GB |
| Move DigiKam DB to 14TB | 5.5 GB |
| Move Frigate to 14TB | 0.9 GB |
| Move VS Code extensions to 14TB | 1.9 GB |
| **Total moved to 14TB** | **~20 GB** |
| **GRAND TOTAL FREED FROM OS DRIVE** | **~38–42 GB** |

After all steps, the OS drive should drop from **86% → roughly 55–60% full**,
giving you ~55–65 GB of breathing room.

## Bonus Tips

- **Your 469 GB Intel SSD at `/mnt/INTEL-SSD` is nearly empty** (only 449 MB used of 469 GB).  
  Consider using it for speed-sensitive data like VS Code, DigiKam DB, or your home `~/.config` folder — SSDs are much faster than the spinning 14TB hard drive.

- **Brave Browser appears twice:** you have it installed both as a native app (`/opt/brave.com`, 429 MB) and as a Flatpak (`~/.var/app/com.brave.Browser`, 3.7 GB). You are likely only using one. Running `flatpak uninstall com.brave.Browser` would free ~3.7 GB if you use the native version.

- **Make sure `/mnt/14TB-HD` auto-mounts at boot** so symlinks don't break. Check with:
  ```bash
  grep 14TB /etc/fstab
  ```
  If there's no entry, the drive may only mount when you log in — ask Claude to help add a permanent fstab entry.
