+## File Storage Location
+
+**Storage Path:**
+```
+/Users/accusys/Downloads/:user_id/:filename
+```
+
+**Example:**
+```
+/Users/accusys/Downloads/accusys/Carousel01.png
+/Users/accusys/Downloads/accusys/ExaSAN-DAS_System_Code.bin
+```
+
+---
+
+## Upload Response
+
+**Success Response (JSON):**
+```json
+{
+  "ok": true,
+  "filename": "example.bin",
+  "file_size": 1048576,
+  "file_hash": "sha256_checksum...",
+  "user_id": "accusys",
+  "stored_at": "/Users/accusys/Downloads/accusys/example.bin",
+  "timestamp": "2026-06-09T..."
+}
+```
+
+---
+
+## Viewing Uploaded Files
+
+**Command Line:**
+```bash
+# List all uploaded files
+bash /Users/accusys/markbase/scripts/list_uploaded_files.sh
+
+# View file directory
+ls -lth /Users/accusys/Downloads/accusys/
+
+# Check file SHA256
+shasum -a 256 /Users/accusys/Downloads/accusys/filename.ext
+```
+
+---
+
+## Best Practices for Batch Upload
+
+### Recommended: Upload by Series
+
+**Example Structure:**
+```
+Folder to upload: ExaSAN-DAS
+├── ExaSAN-Carry-12/
+│   ├── System_Code_v1.0.bin
+│   ├── Boot_Code_v1.0.bin
+│   ├── MacOS_10_15_Installer.dmg
+│   └── Windows_Installer.exe
+├── Max24/
+│   ├── System_Code.bin
+│   └── Driver_Windows.exe
+└── ExaSAN-LTO/
+    ├── LTFS_Tools_MacOS.dmg
+    └── LTFS_Tools_Windows.exe
+```
+
+**Upload Steps:**
+1. Select `ExaSAN-DAS` folder
+2. All files in subfolders will be uploaded
+3. File paths flattened to `/Users/accusys/Downloads/accusys/`
+
+### Upload All 290 Files
+
+**Strategy:**
+- Upload one series at a time (6 series)
+- Monitor progress for each batch
+- Verify SHA256 checksums
+- Total estimated time: 10-30 minutes (depends on network)
+
+---
+
+## Limitations
+
+### Current Limitations:
+- ⚠️ **No subfolder preservation**: Files flattened to single directory
+- ⚠️ **No download URL**: Download service not yet implemented
+- ⚠️ **No file metadata**: Filename only (no product/type info)
+
+### Future Improvements:
+- ✅ Download URL service (planned)
+- ✅ Product/file metadata database (planned)
+- ✅ Folder structure preservation (planned)
+
+---
+
+## Troubleshooting
+
+### Upload Fails
+- Check user_id is correct
+- Verify file permissions
+- Check disk space: `df -h /Users/accusys/Downloads/`
+
+### Browser Compatibility Issues
+- Use Chrome/Edge for best results
+- Enable Firefox setting if needed
+- Check browser console for errors
+
+### Large File Upload
+- No size limit (tested with 100GB+)
+- Progress bar may freeze temporarily
+- Wait for completion message
+
+---
+
+## Testing
+
+**Test Commands:**
+```bash
+# Test upload API
+echo "test" > test.txt
+curl -X POST https://download.accusys.ddns.net/api/v2/upload-unlimited/accusys \
+  -F "file=@test.txt" | jq '.' 
+
+# Test health check
+curl https://download.accusys.ddns.net/api/v2/health | jq '.' 
+```
