+# Remove `mimetype` from `EncryptedFile` object
+
+
+## Proposal
+The example in the spec currently lists `mimetype` in the [examples for `EncryptedFile`](https://matrix.org/docs/spec/client_server/r0.6.1#extensions-to-m-message-msgtypes) but not in
+the object definition. As that is duplicate information of the `info` block of file events, the
+mimetype should just be removed alltogether.
+
+
+## Potential issues
+Some clients might depend on this.  However, as of August 2021, all known clients have
+been confirmed to not use this.
