WinSQL, developed by Synametrics Technologies, is a database management application for Microsoft Windows. The .OBAK file extension identifies an offline backup created by WinSQL.
An OBAK file is intended to be used as part of WinSQL's backup and recovery workflow rather than as a general-purpose document. Its contents can be restored or otherwise managed through WinSQL on Windows.
Open an OBAK file with WinSQL on Microsoft Windows. Use WinSQL's backup or restore features to access the data; the file is not intended to be opened as plain text or by a general file viewer.
To obtain data in another format, restore the backup in WinSQL and export or copy the restored data using the database tools available there.
