What is an MBS file?

MBS files mostly belong to Opera by Opera. An MBS file is a mailbox created by the Opera Mail client built into Opera browser. A mailbox comprises data organized by account and month, containing both in- and outgoing messages. Opera will automatically compress an MBS file when a certain percentage of the messages in them are deleted. Another type of MBS file is a compressed archive of web pages created and accessed using Simotion motion control system. Web pages saved in an MBS file makeup a programmable logic controller's server administration interface. Scenes used in Isotiles puzzle game are saved in MBS files.
