+=== Deleting Video Files
+
+Selenoid intentionally has no built-in logic to automatically remove old video files. To limit storage space consumption you have two alternatives:
+
+. Schedule scripts automatically removing files older than desired date and time. An example command under Unix operating systems can look like:
+
+    $ find /path/to/video/dir -mindepth 1 -maxdepth 1 -mmin +120 -name '*.mp4' | xargs rm -rf
+
++
+Notice `-mmin +120` argument meaning to only process files older than 2 hours (120 minutes).
+
+. Send video removal requests (e.g. from passed test cases). Just use `DELETE` HTTP method and Selenoid video URL:
+
+    $ curl -X DELETE http://selenoid-host.example.com:4444/video/<filename>.mp4
