What is a DBB file?

A DBB file contains information about a user of Skype, a telecommunications application. It stores a user profile, contact list, and chat history information. Recent versions of Skype no longer use DBB files; they use .DB files (e.g., main.db, skype.db, and database.db).

More Information

Niklas Zennström, Janus Friis, Priit Kasesalu, Toivo Annus, Ahti Heinla, and Jaan Tallinn initially developed and released Skype in 2003. Several companies have acquired and sold the technology through the years, with Microsoft currently maintaining the telecommunications software (and introducing the DB format to replace DBB files).

While recent versions of Skype no longer use the DBB format, you may still encounter the files if you previously used older versions of Skype. If you have an older version of Skype installed on your computer, you can find your DBB file in one of the following locations (depending on the Windows version you are using):

  • C:\​Documents and Settings\​[Profile Name]\​Application Data\​Skype\​[Skype User]
  • C:\​Documents and Settings\​[Profile Name]\​AppData\​Roaming\​Skype\​[Skype User]

Common DBB Filenames

chatmsg256.dbb - Filename of the DBB file that stores a Skype user's information.

How to open a DBB file

DBB files are not meant to be opened. Instead, older versions of Skype reference the information in the DBB file to load it into the app upon startup.

However, if you want to view the information in a DBB file without Skype, several utilities are available. For example, you can use skypr or NirSoft SkypeLogView to view information, such as chat history or incoming and outgoing calls, in a DBB file.

How to convert a DBB file

NirSoft SkypeLogView can convert DBB files to the following formats:

  • .TXT - Plain Text File
  • .CSV - Comma-Separated Values File
  • .XML - XML File
  • .HTML - Hypertext Markup Language File
