How to Use

Analyze Files

"Analyze these files and suggest how to organize them"
"What category does this file belong to?"
"Suggest a better filename for this document"

Organize

"Create a folder structure for my project files"
"Organize my downloads folder"
"Sort these invoices by vendor and date"

Naming Conventions

Recommended Formats

Documents

YYYY-MM-DD_Category_Description_v1.ext
Example: 2026-01-29_Contract_ClientName_NDA_v1.pdf

Images

YYYY-MM-DD_Event/Project_Description_NNN.ext
Example: 2026-01-29_ProductLaunch_HeroImage_001.png

Invoices/Receipts

YYYY-MM-DD_Vendor_Amount_InvoiceNumber.ext
Example: 2026-01-29_Adobe_149.99_INV-12345.pdf

Meeting Notes

YYYY-MM-DD_MeetingType_Topic.ext
Example: 2026-01-29_TeamSync_Q1Planning.md

Naming Rules

Use underscores or hyphens, not spaces
Start with date for chronological sorting
Include key identifiers (client, project, type)
Add version numbers for iterations
Keep names concise but descriptive

|--------------|----------|-------------|
| IMG_1234.jpg | 2026-01-29_ProductPhoto_001.jpg | /Products/Photos/ |
| doc1.pdf | 2026-01-15_Contract_ClientA_NDA.pdf | /Clients/ClientA/Contracts/ |

### Actions Required
1. Create folders: [list]
2. Rename files: [count]
3. Move files: [count]
4. Review manually: [count with reasons]

Duplicate Report

### Exact Duplicates
| File | Locations | Size | Recommendation |
|------|-----------|------|----------------|
| report.pdf | /Downloads/, /Documents/ | 2.3MB | Keep in /Documents/ |

### Similar Files
| Files | Similarity | Difference |
|-------|------------|------------|
| report_v1.pdf, report_v2.pdf | 95% | v2 has extra page |

Analysis Capabilities

Content-Based Categorization

Documents: Contracts, reports, letters, forms
Financial: Invoices, receipts, statements, budgets
Media: Photos, videos, audio, graphics
Code: Source files, configs, documentation
Data: Spreadsheets, databases, exports

Metadata Extraction

Creation/modification dates
Author information
File dimensions (images/video)
Duration (audio/video)
Page count (documents)

Automation Rules

Example Rules

## Auto-Organization Rules

### Rule 1: Invoices
- Trigger: PDF with "Invoice" or "INV-" in content
- Action: Move to /Finance/Invoices/[Year]/[Month]/
- Rename: YYYY-MM-DD_Vendor_Amount.pdf

### Rule 2: Screenshots
- Trigger: File matches "Screenshot*.png"
- Action: Move to /Screenshots/[Year-Month]/
- Rename: YYYY-MM-DD_HH-MM_Screenshot.png

### Rule 3: Downloads Cleanup
- Trigger: File in Downloads older than 30 days
- Action: 
  - If document → Archive
  - If installer → Delete
  - If media → Sort to appropriate folder

Best Practices

Organization Principles

PARA Method: Projects, Areas, Resources, Archive
Date-First: Enables chronological sorting
Descriptive Names: Future you will thank you
Flat is Better: Avoid deep nesting (max 3-4 levels)
Regular Maintenance: Schedule monthly reviews

File Hygiene

Delete duplicates and temp files
Archive completed projects
Use cloud sync for important files
Maintain consistent naming
Document your system

Limitations

Cannot access protected/encrypted files
Large file moves require manual execution
Content analysis depends on file format support
Cannot guarantee perfect categorization
Manual review recommended for important files
