Media management

Tuwunel provides a set of admin room commands for inspecting and deleting media. All commands are invoked in the admin room and prefixed with !admin media.

Inspecting media

get-file-info

!admin media get-file-info <mxc_uri>

Returns the stored metadata for a media file: content type, file size, creation time, and which user uploaded it. Useful for investigating a reported file before deciding whether to delete it.

get-remote-file

!admin media get-remote-file <mxc_uri> [-s <server>] [-t <timeout_ms>]

Fetches a remote media file from the originating server and returns its metadata. The actual content is discarded after fetching so the admin room is not flooded. Default timeout is 10 000 ms.

get-remote-thumbnail

!admin media get-remote-thumbnail <mxc_uri> \
  [-s <server>] [-t <timeout_ms>] [--width <px>] [--height <px>]

Like get-remote-file but requests a thumbnail at the given dimensions (default 800×800). Useful for confirming what a thumbnail looks like without sending it to a client.

Deleting media

Delete a single file

!admin media delete --mxc mxc://example.com/AbCdEfGhIjKl

Removes one media file from the database and from storage. Use get-file-info first to confirm you have the right MXC URI.

Delete media referenced by an event

!admin media delete-by-event --event-id $abc123:example.com

Extracts all MXC URIs from the event (including the primary media URL, thumbnail URL, and encrypted file URL) and deletes each one. Returns the number of files deleted. Useful when a user reports a specific message containing unwanted media.

Delete a list of MXC URIs

Paste a code block of MXC URIs into the admin room, one per line:

!admin media delete-list
```
mxc://example.com/AbCdEfGhIjKl
mxc://example.com/MnOpQrStUvWx
mxc://badserver.tld/YzAbCdEfGhIj
```

Errors on individual URIs are ignored. The command returns the total number deleted and the number that failed to parse.

Delete by time range

!admin media delete-range <duration> --older-than
!admin media delete-range <duration> --newer-than

Deletes remote media whose filesystem modification time falls outside the given duration from now. Exactly one of --older-than or --newer-than must be specified.

Duration format: 30s, 5m, 2h, 7d, etc.

By default only remote media is deleted. To also delete locally-uploaded media, append the confirmation flag:

!admin media delete-range 90d --older-than --yes-i-want-to-delete-local-media

Examples:

# Delete all remote media older than 30 days
!admin media delete-range 30d --older-than

# Delete remote media uploaded in the last hour (e.g. after a spam burst)
!admin media delete-range 1h --newer-than

Delete all media from a local user

!admin media delete-all-from-user <username>

Deletes every media file uploaded by the named local user. The username is the localpart only, without the @ or server name. Errors on individual files are ignored.

Delete all media from a remote server

!admin media delete-all-from-server <server_name>

Deletes every cached copy of remote media originating from the given server. This only affects remotely-fetched media by default. To also remove local uploads that somehow reference the server, add the confirmation flag:

!admin media delete-all-from-server <server_name> \
  --yes-i-want-to-delete-local-media

Responding to a spam incident

The full incident playbook (cached-media delete, federation blocks, invite gating, and the per-room policy-server option) lives in Policy and Moderation > Responding to a spam incident. That chapter is the source of truth; refer to it when an incident is in progress.
