Selects the storage backend used by the platform for uploaded files and attachments. The chosen provider determines where files are physically stored.

Storage Provider

Select a registered File Storage Provider from the dropdown. Available providers are discovered automatically from installed plugins and may include:

Local Filesystem – Stores files on the server's local disk.
Amazon S3 / Compatible – Stores files in an S3-compatible object store (requires the S3 Compatible Storage plugin to be configured).
Google Cloud Storage – Stores files in a GCS bucket (requires the Google Attachment Configuration plugin to be configured).

Changing the storage provider after files have been uploaded will not migrate existing files to the new location. Ensure the new provider is fully configured and tested before switching in a production environment.
