DBB files mostly belong to Skype. DBB files are used in several distinct ways.

Other applications of the DBB extension include:

Driver Installation Files: A DBB file may be a ZIP-based archive containing driver packages, often associated with software like dbinst.exe or DriverPack Solution.

SQLite Database Files: Some DBB files use an SQL structure. They can be opened with SQLite viewers. More information is available at SQLite.

Bank Payment Files: Certain DBB files record bank payment data in a format such as the MYOB BankLink file. Additional details can be found on the Digital River page.

BeadTool Pattern Files: In some cases, the DBB extension denotes a beading pattern file format, used to store design patterns (see DBE).

SQL Server Backup Files: A limited number of DBB files serve as backup files for Microsoft SQL Server; further info is available at Microsoft SQL Server.

FilExt.com tip: The extension supports different internal formats such as ZIP or SQL based structures, which means the method to open and view the file depends on its source application. Always check the file origin to use the proper software or tool.

DBB file format details:

Every file has a defined file format, i.e. how the data is arranged in the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. When there is a problem with a file, the first step to solving it is to determine the file format. Our analysis of the DBB files produces the following result:

The DBB file extension is used very often and includes various formats for various programs. However, the following two file formats are common:

• 55% of all DBB files are associated with Skype user data. The contents of these files cannot be read by a human; only a computer program can interpret the data. A typical file size is 4 KB. The file type was primarily used more than 10 years ago. A common filename is call256.dbb or chatmsg256.dbb. Such DBB files store data about chat, user, contactgroup, profile, callmember, chatmember, transfer and voicemail.
• 20% of all DBB files are based on the zip format, the DBB file contains a number of compressed files. A DBB file can contain up to 180 files (mostly 3 - 60). File names are e.g. dbinst.exe, dpinst.exe and meta. Tip: If you rename the file ending to .zip and then double-click it, you see the included files and images. Most of these files are 340 KB to 130 MB in size. Such files are related to intel, controller, acpi, audio, realtek, definition, bluetooth, adapter, family, radeon and high.

The remaining 25% of all DBB files are files with no common format, frequently e.g. SQL and TAPE. These files are often connected to backup, fishmap, wireless, feature, generic, button or fixed.
