What is a TBB file

TBB files mostly belong to BlackBerry Desktop Software. TBB files are not a single standard file type but can serve different roles depending on their origin.
In many cases, a TBB file is used as a backup archive created by BlackBerry Desktop Software, which stores data from a mobile device for later restoration.
In other scenarios the same extension appears as an email folder file used by clients like Thunderbird or The Bat!, packaging collections of email messages.
Additionally, some TBB files are employed in gaming. They serve as a Tabular Binary Container (also called a Binary Table File) that holds various game assets, as seen with titles such as Shin Megami Tensei V and The House of the Dead 2.
Key uses include:

Backup for mobile device data

Email folder storage

Game data container for resource files

FilExt.com tips: It is vital to first identify the file’s origin to choose the proper software for opening it. For mobile backups, use BlackBerry Desktop Software; for game data, specialized mod or extraction tools may be required. You may also find further details on the file’s role from its source, for example on the BlackBerry website or related game sites like Sega.

TBB file format:

Each file has a definite file format, that is, how the stored data is arranged in the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. So you need a detailed analysis of a file to find out the format and the associated program. Our evaluation of the TBB files looks like this:

The TBB file extension is not found very often and includes different formats for the applicable programs. The two most common formats are as follows:

• 35% of all TBB files are associated with The Bat! Message Base. These files contain text and words, not binary data. The files are 8 KB to 1 GB in size, with a median of 9 MB. The file type is old but is used even today. The file name MESSAGES.TBB is typical for these files.
• 20% of all TBB files have the same signature TB. The contents of these files cannot be read by a human; only a computer program can interpret the data. The file size is in the range of 96 bytes to 160 KB. Several words can almost always be found in the files, e.g. TBL1, TBB1 and TBCR. Some examples of file names are ItemTable.tbb. Files like these are about help and data.

All other TBB files (45%) have no uniform format, often e.g. BTbl. These files are often connected to font or backup. You can get all the details of your TBB file by dragging it onto this page or by clicking the button "Choose your .tbb file to analyze" above.
