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.
File Security
Data and permissions around files are associated to the directus_files
collection.
It is recommended that you only provide public permissions to specific files or file folders (for example, a 'Public' folder), rather than making the whole collection public. Read more on custom access permissions.
Exporting Data Creates Files
Exporting data creates new files and adds them to your file storage. If these files are accessible publicly, you may leak data held in the exported collections.
Accessing a 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
example.com/assets/<file-id>
example.com/assets/1ac73658-8b62-4dea-b6da-529fbc9d01a4
SEO
You can provide an optional filename after the UUID to optimize for SEO, for example:
example.com/assets/<file-id>/<filename>
example.com/assets/1ac73658-8b62-4dea-b6da-529fbc9d01a4/directus-logo.png
example.com/assets/<file-id>/<filename>
example.com/assets/1ac73658-8b62-4dea-b6da-529fbc9d01a4/directus-logo.png
This optional filename is also used in the Content-Disposition header when the ?download
query parameter is used.
Direct File Access
While you may technically be able to expose your storage adapters root file system 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 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>
<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 Data Studio, 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 ofauto
,jpg
,png
,webp
,tiff
auto
— Will try to format it inwebp
oravif
if the browser supports it, otherwise it will fallback tojpg
.
Advanced Transformations
For even more advanced control over the file generation, Directus exposes the full sharp
API through the transforms
query parameter. This parameter accepts a two-dimensional array with the format [Operation, ...arguments]
.
Quality vs File Size
The quality parameter can be any integer from 0-100
. Qualities closer to 0
have lower file sizes, but also poor image quality due to compression artifacts. Values closer to 100
have larger file sizes, but better image quality. Below are four possible qualities (200x200 cover) to visually compare the balance between compression and file size.
25% | 50% | 75% | 100% |
---|---|---|---|
4KB | 6KB | 8KB | 38KB |

Focal Points
Directus will crop assets when requested with a width
or height
query parameter. By default, images are cropped around the center of the image. If focal_point_x
and focal_point_y
values are stored in the file object, cropping will center around these coordinates.
