What is a PB2 file?

PB2 files mostly belong to Protocol Buffer Editor. PB2 files are specialized data files that can serve two main roles. They may be used as a phonebook file format, storing contact information for certain applications, or as a Protocol Buffer description file that contains data schema definitions used to serialize structured data.

Phonebook File Format: This version of the file may include details like names and phone numbers. It is intended for systems managing contact lists.

Protocol Buffer Description File: In this case, the file holds definitions for data serialization. Such files help applications exchange and interpret data efficiently.

The file is not plain text and requires specialized software to view or edit. For protocol buffer descriptions, a dedicated tool such as the Protocol Buffer Editor is often used. If it is used as a phonebook file, you might need a compatible contact management application.
FilExt.com note: Remember to always backup your file before editing. A quick check with a hex editor might reveal clues to its true structure if you are unsure which role it is fulfilling.
