BBB is short form of BlackBerry Backup. This file extension is used for backup files used by BlackBerry devices.
The type and amount of data stored in this file can vary and depends upon the preference of the person using backup. Generally there are two types of data stored in BBB file; the device configuration settings which are either done by the user or are set by the factory and the personal data of the person stored in BlackBerry device. If the data on the device is lost or is corrupted then BBB files are used by the device to restore either whole data or limited number of files.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .BBB file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .BBB file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .BBB file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
