What is a BACK file?

BACK files mostly belong to Backup utility. BACK files are backup copies that store data from different applications in a safe way.
They can serve several purposes:

Video backups in MP4 format created by media players like VLC Media Player, which may hold video fragments used temporarily.

Program backups such as those made by tools like Guitar Pro or Tabular Editor 3. These files hold program state or settings.

Database backups using formats like SQL. For example, a SQLite backup file (SQLite) or a Microsoft SQL Server backup (SQL Server) stores structured data.

Executable or program file copies saved as backup (EXE) to restore software.

Financial or mobile backups such as those used by MoneyWiz 3 or Apple Wallet for iOS/macOS.

Compressed archives in ZIP format, as seen in backups handled by applications like WinZip, or in GZIP format for backup copies such as those used by Grapholite (Grapholite).

The purpose is to create a restore point in case the original data is lost or changed. To open these files, use the same software that created them. If the file is made with a video tool, open it with that media player; if it is a database backup, use the relevant database utility.
FilExt.com note: This file type often uses its native format (MP4, SQL, EXE, ZIP, GZIP) so you might need to rename the file or change the extension to match what your software expects before opening it.

BACK file extension format:

A file format defines how the data in the file is structured. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Knowledge is power - this also applies when dealing with unknown or faulty files. Our examination of the BACK files comes to the following conclusion:

The file type with the extension 'BACK' does not have a uniform file format. However, the following two file formats are common:

15% of all BACK files start with the magic bytes eyJ, which are always the first bytes of this file format. If you open these files in a text editor, you can view and read the content yourself. BACK files are between 570 bytes and 22 KB in size. The file type was created recently. Several words can almost always be found in the files, e.g. eyJzdGF, bGwsbnVsbF, bGwsbnVsbCxudWxsLG, YWJzIjp, IjAiOnsibm, bGxdLFtudWxsLG, RlcyI and YWJzIjpbeyJub. Some examples of file names are tabmaker_com-backup.back or tabmaker_com-backup (1).back. Such files are related to tabmaker and backup.
10% of all BACK files are based on the well-known MP4 file format. MP4 is a multimedia container format used to store video and audio and allows streaming over the Internet. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. The files are often between 870 KB and 11 MB in size. The keywords free, ftypisom, isomiso2avc1mp41, core, Copyleft 2003-2017, MPEG-4 AVC codec - Copyleft 2003-2017 - http, html - options, http://www.videolan.org/x264.html and mdat are typical for these files. A usual file name is SVID_20180601_1.mp4.back.
