What is a B1 file?

B1 is an open format and an open-source command-line archiving tool, B1 Pack, has also been made available by the developers.

Other uses: B1 is an extension associated with the Progress database, a database from Progress that is at the back-end of many Progress and third-party products. The B1 file is a recovery data (back-image) file and stores a record of transactions so that the database can be rolled back in case of hardware failure. There may be more than one back-image files, in which case they are numbered B1, B2, B3, and so on.

OpenEdge (recovery data file) by Progress
OpenEdge is a Relational Database Management System (RDBMS) from Progress. The system is built on the Progress database. Several other Progress products also make use of this database (ex: DataDirect). In addition to Progress products, the Progress database is also at the back end of several third-party applications. B1 is a primary recovery (before image) file associated with the Progress database. B1 keeps a record of all transactions so that the database can be rolled back in case of a hardware problem. There may be multiple files with Bn extensions (n being a sequential number). Files with similarly-named extensions (DB, D1, D2,...) have a different format to B1. They are files that store the data in the Progress database. This file format is classified as Data. Related links: Progess Database Guide, Progress Software on Wikipedia
