Duplicate Asset Finder

Location: Tools -> Nexus Graph -> Visualizers -> Duplicate Finder

In large production teams, accidental duplication is common. An artist might drag Texture_Final.png into a new folder named Texture_Final_V2.png. Unity treats these as two separate assets, doubling your memory usage and build size.

The Duplicate Asset Finder solves this by performing a Content-Based Scan rather than a Name-Based scan.

How it Works

MD5 Binary Hashing

The tool reads the raw byte content of files and generates an MD5 hash.

If File A and File B have the same hash, they are identical, regardless of their filename or location.

Features

1. Fresh Scan

Click Re-Scan Duplicates to perform a fresh traversal of the project.

Note: This process reads file bytes and may take a moment for projects with gigabytes of data.

2. Grouped Results

Duplicates are displayed in groups.

Original: The first instance found (usually the one you want to keep).
Copies: The subsequent instances.

3. Resolution Strategy

Once duplicates are identified:

Select the “Copy”.
Use Right-Click -> Find References (or use the Dependency Graph) to see where it is used.
Remap those references to the “Original” asset.
Delete the “Copy”.

Future versions will include an Auto-Remap feature.
