.OZ File Extension

Compressed file created by Opera Job Management, an application used to manage and inspect the production of doors and windows; contains backup data generated by the software; stores the contents in a proprietary format, which uses Gzip libraries; used for backing up and sharing application data as attachments of auto-generated emails.

OZ files are created using the oz.exe utility, which is included with Opera Job Management. They can also be generated on older DOS machines using the ozdos.exe 8-bit version of the utility.

NOTE: Opera Job Management is a Windows application, but it can also run in Linux with Wine installed.
