The primary data container is the main virtual application file that includes the ThinApp runtime and the read-only virtual file system and virtual registry.

The primary data container file is a .exe or a .dat file that resides in the same /bin directory with any subordinate application executable files. Entry points reference the information in the primary data container.

To identify the primary data container after you capture an application, check the ReadOnlyData parameter in the Package.ini file.
