What is an OCB file?
An .OCB file can represent several different formats. Most often, an .OCB file is a BIOS overclocking profile created by MSI motherboards or the MSI Command Center software. These files store custom hardware settings. Another common use is for configuration backups created by Directory Opus, a file manager for Windows. In this case, the .OCB file is actually a .ZIP archive containing application settings. An .OCB file can also be an Oxygen Forensics Cloud Backup created by Oxygen Forensics, or an organizational chart data file used by Epicor HCM.
How to open OCB files?
Because an .OCB file has multiple possible meanings, you need to know its origin to open it correctly. To open an MSI BIOS profile, you must load it through the MSI BIOS interface. To open a Directory Opus backup, you can rename the file extension to .ZIP and extract it with standard archive tools like 7-Zip. For an Oxygen Forensics Cloud Backup, you need specific digital forensics software from Oxygen Forensics.
