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 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

html
<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 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

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 fit
    • contain — Contain within both width/height using "letterboxing" as needed
    • inside — Resize to be as large as possible, ensuring dimensions are less than or equal to the requested width and height
    • outside — 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 pixels
  • height — The height of the thumbnail in pixels
  • quality — The optional quality of the thumbnail (1 to 100)
  • withoutEnlargement — Disable image up-scaling
  • format — What file format to return the thumbnail in. One of auto, jpg, png, webp, tiff
    • auto — Will try to format it in webp or avif if the browser supports it, otherwise it will fallback to jpg.

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.

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.
