Introduction

After an investigation, you might have hours of video, multiple audio files, hundreds of photos, and pages of notes. If you don’t organize them right away, valuable context will be lost, and reviewing the evidence will become a nightmare.

This lesson will teach you how to create a clear, logical evidence management system so every file can be found, referenced, and reviewed quickly.

Why Organization Matters

  • Preserves Context – Keeps events tied to the right time, place, and conditions.

  • Saves Time – Faster review and analysis.

  • Protects Evidence Integrity – Prevents accidental deletion or mislabeling.

  • Supports Professional Reports – Makes your findings easy to present to clients or the public.

Step 1 – Back Up Immediately

  • Create at least two backups: one on an external drive and one on cloud storage.

  • Do this before you start reviewing files.

Step 2 – Use a Consistent Folder Structure

Example investigation folder:

css
[Location]_[Date]
│
├── Audio
│ ├── Raw
│ └── Cleaned
├── Video
│ ├── Stationary_Cams
│ └── Handheld
├── Photos
│ ├── Baseline
│ └── Anomalies
└── Notes

Step 3 – File Naming Conventions

Use clear, uniform names that include:

  • Location

  • Date (YYYY-MM-DD format)

  • Device or Camera ID

  • Time (24-hour format)

Example:
HotelMason_2025-08-14_Cam2_22-37.mp4

Step 4 – Sync Evidence with Notes

  • Match audio/video timestamps to logbook entries.

  • This allows you to quickly locate events mentioned during the investigation.

Step 5 – Keep Raw Files Untouched

  • Always preserve an unaltered copy of every file.

  • Do editing or filtering only on duplicates.

Pro Tips for Efficient Organization

  • Assign one person as the Evidence Manager for each investigation.

  • Store investigation logs digitally (scan paper copies).

  • Color-code folders or tags for “Needs Review,” “Flagged,” and “Final Evidence.”

Case Study

A team investigating a historic courthouse kept all their audio files in one unorganized folder. Weeks later, they couldn’t match a potentially clear EVP to its location or time. After adopting structured folders and naming conventions, their evidence review time dropped by 40% and they never lost a file again.

Action Step Before Moving On

  • Set up a sample folder structure on your computer for a hypothetical investigation.

  • Create at least one sample audio, video, and photo filename using the convention above.

Closing

Organizing your evidence is the foundation for an effective review. Without it, you risk losing context, credibility, and potentially your best captures.

In the next lesson, 6.2 – Reviewing Audio, we’ll start digging into one of the most time-consuming but rewarding parts of the post-investigation process — finding EVPs and other audio anomalies.
