ThinApp User’s Guide : Configuring Package Parameters : Configuring Individual Applications : ReadOnlyData

ReadOnlyData
The ReadOnlyData parameter specifies the name of the read-only virtual registry file created during the application build and designates the primary data container for an application.
Do not modify this parameter. The Package.ini file displays this parameter in case you want to find the primary data container.
When the primary data container is less than 200MB, ThinApp stores the container within an entry point executable file. When the primary data container is more than 200MB, ThinApp stores the container as a .dat file that cannot serve as an entry point for the application.
Examples
ThinApp sets the required value of the ReadOnlyData parameter that specifies Package.ro.tvr as the name of the virtual registry file.
ReadOnlyData=bin\Package.ro.tvr
