Engine behaviour

The Data Type Registry engine has the following behaviours:

Initially scans the registry directory for valid registrations files and parses them.
Rescan the registry directory when changes are detected on the file system.
Extension check will succeed if a file name ends with a dot followed by the Extension. Case is ignored.
Extension check gives possible recognition results.
Signature check will succeed if the Signature is found in the file content at the specified Offset.

If a Signature is specified Extension check will be disabled.
