FileMagic’s commitment to non-destructive file viewing is another key benefit. Some applications attempt to convert or modify a file during the viewing process, which can lead to data corruption or format loss. FileMagic never alters the file—what you see is exactly what’s stored on disk. https://www.filemagic.com/en/uncommon-files/b3r-file-extension/how-can-i-open-b3r-files/
