If your file comes from backup software like Acronis True Image, it stores a system or partition backup image. More details are available at Acronis.

Backup Files: Contain disk images used for system recovery.

If the file originates from Adobe Photoshop configurations by Liquidverve, it saves toolbar settings to customize the interface. Further information can be found at Liquidverve.

TBR file format:

To view or edit TBR files you need to know the file format, because it determines how the data in this file is stored. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). If the file extension or signature does not match the file format, errors will occur when opening or editing the file. If there are problems opening a file, you must first determine the file format used. Our evaluation of the TBR files is as follows:

TBR is seldom used as a file extension and includes different formats for different programs. The file formats most commonly found in TBR files are:

• 40% of all TBR files start with the magic bytes eyJhbGciOiJSUzI1NiJ9.eyJlbnZpcm9ubWVudCI6InByb2QiL, which are always the first bytes of this file format. These files are plain text, which means they can be viewed with any text editor such as Windows Editor, Nano for Linux, and TextEdit for macOS. TBR files are between 460 bytes and 500 bytes in size. The file type is very recent. The files contain the following words: FkIjoidTBWT, InByb, MiOiJwY, MyWHJwSUh, QiLCJpc, dFkyWE, eyJhbGciOiJSUzI1NiJ9, eyJlbnZpcm, ubWVudCI and zdWkiLCJleHBvcnRQYXlsb. The file name Chapter 1.tbr is characteristic of these files. Such files are related to exam, quiz, bank, midterm, spring and term.
• 15% of all TBR files start with the bytes EFBD, which are crucial for this file format. These files are binary files, so they do not contain text, but only cryptic characters. The files are often between 70 MB and 39 GB in size. The following keywords are characteristic: EFBD. Files like these are about backup, computer, volumes and disk.

All other TBR files (45%) have no uniform format, often, for example, XML and null. Often described as toolbar or tool. If you want to find out what your TBR file contains, drag and drop it onto this page.
