+# cgitta Nextcloud – Storage Cleanup (Completed 2026-05-09)
+
+**Starting size:** 418 GB  
+**Final size:** ~26 GB  
+**Total freed:** ~392 GB  
+
+---
+
+## What Was Done
+
+### 1. Corrupt / Unreadable Archives — Deleted (82.9 GB)
+Both were first-segment-only multi-part zip archives with missing parts — completely unreadable.
+
+| File | Size | Action |
+|------|------|--------|
+| `Documents.zip` | 75 GB | Deleted — content already in Documents/ folder |
+| `OneDrive-2024-10-31.zip` | 7.9 GB | Deleted — unreadable, content verified elsewhere |
+
+### 2. Google Takeout Zips — Deleted (75 GB)
+8 takeout zip files from Feb 2023 export. Zip 001 (Google Photos/Keep/Drive/Contacts) and Zip 008 (Gmail mbox) were already fully extracted. Zips 002–007 (Google Photos videos) were extracted then deleted.
+
+All 8 zips removed after confirming extraction.
+
+### 3. Duplicate Zips — Deleted (~293 MB)
+- 9 exact duplicate `(1)`/`(2)` browser re-downloads removed
+- `Photos.zip` and `Photos-001.zip` confirmed duplicated in Documents/Photos/ and removed
+
+### 4. Gmail Backup
+- Extracted `gmail-backup.tar.gz` (30 GB tar → 3.1 GB mbox) to `Backup Files/Gmail/`
+- Deleted the original tar
+
+### 5. Google Drive Content Consolidated
+- Drive folders from 7 Takeout sub-archives merged into `Documents/Google Drive/` (4.2 GB)
+- Duplicate files across takeout extracts deduplicated with fdupes
+
+### 6. Photos Migrated to Immich (69 GB freed from Nextcloud)
+- All 53,299 files (69 GB) from `cgitta/files/Photos/` rsynced to photos VM staging area
+- fdupes comparison against Joe's Immich library (`/mnt/immich-photos/photos/joe/`):
+  - 3,243 files already in Joe's library → deleted
+  - 1,540 internal duplicates → deleted
+  - **48,676 unique files (55 GB) → moved to `/mnt/immich-photos/photos/cynthia/`**
+- Immich external library rescanned — photos indexed under Cynthia's account
+- `Photos/` folder deleted from Nextcloud
+
+---
+
+## Final Nextcloud State (cgitta account)
+
+| Folder | Size |
+|--------|------|
+| Documents | 18 GB |
+| zip drives (teaching materials) | 2.6 GB |
+| Video | 463 MB |
+| music | 2.6 MB |
+| **Total** | **~26 GB** |
+
+The `zip drives` folder (~2.6 GB) contains ~100 Teachers Pay Teachers curriculum zips — left intact for Cynthia to review.
