# Deduplication

A unique feature of Egnyte is the deduplication feature, something that can greatly reduce the amount of storage used. 

### How Egnyte determines if files are duplicates

Egnyte determines the duplication of files based on the checksum of each file. Checksums are calculated based on the content of the file. This means that even if a file has a different name but the same content, it would still be flagged as a duplicate. 

Duplicate files are based only on the most recent version of the file, and the SHA-512 hash function is used to calculate the checksum of the files. 

### Storage vs deduplicated storage quota

In the Egnyte Admin settings under the Subscription tab is the Current Usage section. Within that is a breakdown of users and storage. 

Storage is broken down into **Storage (without deduplication)** and **Storage (with deduplication)**. While both of these show a progress bar with a maximum limit, only the **Storage (with deduplication)** counts towards the plan limit. 

**Storage (without deduplication)** is there simply as a guide to show how much storage space is being saved with this feature.
