Directus provides a flexible storage abstraction layer that allows you to store and manage files across different storage providers. This abstraction enables you to seamlessly switch between local file systems and cloud storage services without changing your application code.

​
Storage Architecture

The storage system consists of:
  • Storage Manager - Central management interface for registering drivers and locations
  • Storage Drivers - Provider-specific implementations (Local, S3, Azure, GCS, Cloudinary, Supabase)
  • Storage Locations - Named storage configurations that use a specific driver

​
Available Drivers

Directus supports the following storage drivers:
  • Local - Store files on the local file system
  • S3 - Amazon S3 and S3-compatible storage (DigitalOcean Spaces, MinIO, etc.)
  • Azure - Azure Blob Storage
  • Google Cloud Storage - Google Cloud Storage
  • Cloudinary - Cloudinary media management platform
  • Supabase - Supabase Storage

​
Configuration

Storage is configured using environment variables. You need to:
  1. Define which storage locations to use
  2. Configure each location with a driver and options

​
Basic Configuration

# Define available storage locations
STORAGE_LOCATIONS="local"

# Configure the local storage driver
STORAGE_LOCAL_DRIVER="local"
STORAGE_LOCAL_ROOT="./uploads"

​
Multiple Storage Locations

You can configure multiple storage locations: 
# Define multiple locations
STORAGE_LOCATIONS="local,s3,cloudinary"

# Configure local storage
STORAGE_LOCAL_DRIVER="local"
STORAGE_LOCAL_ROOT="./uploads"

# Configure S3 storage
STORAGE_S3_DRIVER="s3"
STORAGE_S3_BUCKET="my-bucket"
STORAGE_S3_REGION="us-east-1"
STORAGE_S3_KEY="your-access-key"
STORAGE_S3_SECRET="your-secret-key"

# Configure Cloudinary storage
STORAGE_CLOUDINARY_DRIVER="cloudinary"
STORAGE_CLOUDINARY_CLOUD_NAME="your-cloud-name"
STORAGE_CLOUDINARY_API_KEY="your-api-key"
STORAGE_CLOUDINARY_API_SECRET="your-api-secret"
STORAGE_CLOUDINARY_ACCESS_MODE="public"

​
Driver Interface

All storage drivers implement a common interface with the following methods:

​
Core Methods

  • read(filepath, options?) - Read a file as a stream
  • write(filepath, content, type?) - Write a file from a stream
  • delete(filepath) - Delete a file
  • stat(filepath) - Get file metadata (size, modified date)
  • exists(filepath) - Check if a file exists
  • move(src, dest) - Move a file
  • copy(src, dest) - Copy a file
  • list(prefix?) - List files with optional prefix filter

​
TUS Protocol Support

Some drivers support resumable uploads via the TUS protocol:
  • createChunkedUpload(filepath, context) - Initialize a chunked upload
  • writeChunk(filepath, content, offset, context) - Write a chunk of data
  • finishChunkedUpload(filepath, context) - Complete the upload
  • deleteChunkedUpload(filepath, context) - Cancel and delete an upload
All drivers currently support TUS resumable uploads.

​
Resumable Uploads

Directus supports resumable uploads using the TUS protocol. Configure it globally: 
# Enable resumable uploads (default: true)
RESUMABLE_UPLOADS_ENABLED=true

# Set chunk size in bytes (default varies by driver)
RESUMABLE_UPLOADS_CHUNK_SIZE=5242880
Each driver may have its own minimum chunk size requirements. See the individual driver documentation for details.

​
Root Path

Most drivers support a root configuration option to prefix all file paths: 
STORAGE_S3_ROOT="directus/files"
This is useful for:
  • Organizing files in a shared bucket
  • Multi-tenant configurations
  • Separating environments (dev/staging/production)
