CaseMap, developed by LexisNexis, is used to manage and connect case facts, legal issues, and key players. Its ReportBook feature uses .cmrbk files to define reports based on that case information.
A CMRBK file contains ReportBook definition data, such as the settings and structure used to produce a report. It is associated with the report definition rather than serving as the main CaseMap case file.
The format is intended for use with CaseMap on Microsoft Windows and is not generally designed for direct editing outside the application.
Open a .cmrbk file in CaseMap on Microsoft Windows. Use the file-opening command in CaseMap if double-clicking the file does not open it automatically.
Because the file contains ReportBook definition data, it may not be useful when opened as plain text or in a general-purpose document application.
The file is a CaseMap ReportBook definition, so conversion outside CaseMap may lose its report structure and settings.
To obtain a different form of the report, open the definition in CaseMap and generate or export the report using the output options provided by the software.
