Key details as outlined by FilExt.com include:

Secure Storage: The file is designed to prevent manual tampering.

UMB file extension format:

To view or edit UMB files you need to know the file format, because it determines how the data in this file is stored. Often, the file format can be deduced from the file extension or the initial bytes (called the signature).
