# Accessing Files
Every file managed by the platform is uploaded to the configured storage adapter, and its associated metadata is tracked within the
directus_files
system collection. Any requested file transformations are handled on the fly, and are only saved to storage.
# Accessing an File
The location of your actual file originals is based on the project's configuration, but you can consistently access them via the API using the following URL.
example.com/assets/<file-id>
example.com/assets/1ac73658-8b62-4dea-b6da-529fbc9d01a4
Direct File Access
While you may technically be able to expose your storage adapters root filesystem and access your raw files through there, it is recommended that you always use the Directus API. This is the only way that you can take advantage of file permissions and other built-in features.
Original File Used — 602KB and
1800x1200
# Downloading a File
To download an asset with the correct filename, you need to add the ?download
query parameter to the request and the
download
attribute to your anchor tag. This will ensure the appropriate
Content-Disposition (opens new window) headers are added. Without this, the
download will work on the same domain, however it will have the file's "id" as the filename for cross-origin requests.
# Example
<a href="https://your-directus.com/assets/<file-id>?download" target="_blank" download="Your File.pdf">Download</a>
# Requesting a Thumbnail
Fetching thumbnails is as easy as adding a key
query parameter to the original file's URL. In the Admin App, you can
configure different asset presets that control the output of any given image. If a requested thumbnail doesn't yet
exist, it is dynamically generated and immediately returned.
# Preset Transformations
key
— This key of the Storage Asset Preset, a shortcut for the below parameters
# Custom Transformations
Alternatively, if you have "Storage Asset Transform" set to all, you can use the following parameters for more fine grained control:
fit
— The fit of the thumbnail while always preserving the aspect ratio, can be any of the following options:cover
— Covers both width/height by cropping/clipping to fitcontain
— Contain within both width/height using "letterboxing" as neededinside
— Resize to be as large as possible, ensuring dimensions are less than or equal to the requested width and heightoutside
— Resize to be as small as possible, ensuring dimensions are greater than or equal to the requested width and height
width
— The width of the thumbnail in pixelsheight
— The height of the thumbnail in pixelsquality
— The optional quality of the thumbnail (1
to100
)withoutEnlargement
— Disable image up-scalingformat
— What file format to return the thumbnail in. One ofjpg
,png
,webp
,tiff
# Advanced Transformations
For even more advanced control over the file generation, Directus exposes
the full sharp
API (opens new window) through the transforms
query parameter. This
parameter accepts a two-dimensional array with the format [Operation, ...arguments]
.
# Quality vs Filesize
The quality parameter can be any integer from 0-100
. Qualities closer to 0
have lower filesizes, but also poor image
quality due to compression artifacts. Values closer to 100
have larger filesizes, but better image quality. Below are
four possible qualities (200x200 cover) to visually compare the balance between compression and filesize.
25% | 50% | 75% | 100% |

# List Files
List all files that exist in Directus.
# Query Parameters
Supports all global query parameters.
# Returns
An array of up to limit file objects. If no items are available, data will be an empty array.
# Retrieve a File
Retrieve a single file by primary key.
# Query Parameters
Supports all global query parameters.
# Returns
Returns a file object if a valid primary key was provided.
# Upload a File
Upload/create a new file.
To upload a file, use multipart/form-data
as the encoding type, instead of JSON.
The file contents has to be provided in a part called file
. All other properties of
the file object can be provided as parts as well.
Order Matters
Make sure to define the non-file properties first. This ensures that the file metadata is associated with the correct file.
You can upload multiple files at a time by repeating the payload with different contents, for example:
--__X_BOUNDARY__
Content-Disposition: form-data; name="title"
Example
--__X_BOUNDARY__
Content-Disposition: form-data; name="file"; filename="paulo-silva-vSRgXtQuns8-unsplash.jpg"
Content-Type: image/jpeg
// binary data
--__X_BOUNDARY__
Content-Disposition: form-data; name="title"
Another Title
--__X_BOUNDARY__
Content-Disposition: form-data; name="file"; filename="mae-mu-GFhqNX1gE9E-unsplash.jpg"
Content-Type: image/jpeg
// binary data
In JavaScript, this can be achieved using the native FormData
class:
import axios from 'axios';
const fileInput = document.querySelector('input[type="file"]');
const formData = new FormData();
formData.append('title', 'My First File');
formData.append('file', fileInput.files[0]);
await axios.post('/files', formData);
# Query Parameters
Supports all global query parameters.
# Returns
Returns the file object for the uploaded file, or an array of file objects if multiple files were uploaded at once.
POST /files
// Request
Content-Type: multipart/form-data; charset=utf-8; boundary=__X_BOUNDARY__
Content-Length: 3442422
--__X_BOUNDARY__
Content-Disposition: form-data; name="file"; filename="paulo-silva-vSRgXtQuns8-unsplash.jpg"
